Bulletin 1492
Control Circuit and Load Protection
General Information
Technical Information: The Benefits of Limiting Let-Through Energy
Energy Limiting Circuit Breakers Versus Conventional Breakers
The Bulletin 1492-SP line features the unique ability to achieve short circuit interruptions far more effectively than conventional circuit
breakers. In conventional circuit breakers, the short circuit interruption time required is approximately one or two half cycles of an AC sine
wave. When the contacts are open, the resulting arc continues to burn until the current level passes through zero. The arc may re-ignite
because of the insufficient width of the contact gap. The current that flows until the arc is extinguished produces a heating effect proportional
to the I2t value (let-through-energy) of the fault current.
0
1
These devices are designed to substantially reduce the amount of let-through-current and the resulting let-through-energy that can damage
protected components. They have the ability to interrupt short circuit current within the first half cycle of the fault. Limiting let-through-energy
will protect against the harmful effects of over-current and is focused primarily on avoiding the following:
ꢀ Excessive heat
ꢀ Mechanical damage
2
Both of these factors are proportional to the square of the current. Thermal energy is proportional to the square of the RMS value and
magnetic forces are proportional to the square of the peak value. The most effective way to provide protection is to subtantially limit let-
through-energy.This provides the following advantages:
ꢀ Far less damage at the location of the short circuit.
ꢀ Fast electric separation of a faulty unit from the system, especially power supplies connected in parallel that are switched off when the
voltage of the power bus drops below a certain level.
ꢀ Far less wear on the miniature circuit breaker itself. This means more safe interruptions.
ꢀ Better protection of all components in the short circuit path.
3
ꢀ Far wider range of selective action when used with an upstream protective device. (No nuisance shut downs from feeder line interruptions
causing a blackout in all connected branches.)

Bulletin 1492-MC
Circuit Breaker
Product Description
Branch Circuits:
Continuous Current Rating
Bul. 1492-MC circuit breakers are rated in RMS amperes at a 40 °C
(104 °F) ambient temperature per UL 489 (CSA 22.2 No. 5.1). This
temperature is generally used as the average temperature within an
industrial enclosure. If a circuit breaker is applied in a temperature
that exceeds the 40 °C (104 °F) ambient, then the circuit breaker
should be derated. Contact your local Rockwell Automation sales
office or Allen-Bradley distributor for derating information.
Bulletin 1492-MC circuit breakers may be used to protect branch
circuits. A branch circuit is the wiring portion of a system extending
beyond the final overcurrent device protecting the circuit.
0
Guidelines established in NEC, CEC, UL, and CSA should be used
to determine the specific device. For example:
1
The characteristic trip curves are shown on pages 7-8…7-10. The
trip bands shown for each breaker represent current tripping limits
for a circuit breaker and are within the limits established by UL. For
a specific current at 40 °C (104 °F), a circuit breaker will open ("clear
the circuit") automatically at some total time that will be within the
"Minimum" and "Maximum" time shown as the "Minimum" and
"Maximum" curves. For example, page 7-8 shows that a one pole,
15 A, 1492-MC trips in not less than 10 s and not more than 150 s
on a 30 A current. Because the UL standard defines this time
spread, users should not specify exact tripping time. The lower
current portion of the curves (upper left) depict the time to trip due
to thermal action and reflect overload protection of the wire and
connect load. The higher current portion of the curves (lower right)
depicts the trip due to magnetic action of the circuit breaker and
reflects protection due to short circuit level currents.
1) Motor Branch Circuit
Bulletin 1492-MC circuit breakers are not horsepower rated because
they are able to safely interrupt currents far in excess of the locked
rotor value for a selected motor. This ability is recognized in the
codes and standards and is also established by the UL and CSA
tests described in UL 489 and CSA C22.2 No. 5.1 standards.
2
The size of a Bulletin 1492-MC circuit breaker should be determined
following the guidelines for an Inverse Time Circuit Breaker.
References: NEC 430.51 and UL 508A. Also see CEC and
appropriate Canadian Standards.
3
2) Transformer Protection
Bulletin 1492-MC circuit breakers may be used for transformer
protection following the guidelines established.
4
Standard current ratings are, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55,
60, 70, 80, 90, and 100 A.
References: NEC 450 and UL 508A. Also see CEC and appropriate
Canadian Standards.
Application Considerations
5
The selection of a specific ampere rating for a specific application is
dependent on the type of load and duty cycle and is governed by
the National Electric Code (Canadian Electric Code) and UL/CSA. In
general the codes require that overcurrent protection is at the
current supply and at points where wire sizes are reduced. In
addition the codes state that conductors be protected according to
their current carrying capacity. There are specific situations that
require application consideration, such as motor circuit, and
guidelines for the selection for transformer protection.
3) Heater Load, Lighting, and Other Load Protection
Bulletin 1492-MC circuit breakers may be used for protection of
heater loads, lighting loads, and other loads following the guidelines
established.
6
References: NEC Article 31 and UL 508A. Also see CEC and
appropriate Canadian Standards.
Bulletin 1492-MC circuit breakders are "non-100% rated" as defined
by UL 489 Part 7.1.4.2. As such the circuit breaker's rating should
be loaded to no more than 80%, if used with continuous loads.
Coordinated Overcurrent Protection
7
Where an orderly shutdown is required to minimize the hazards to
personnel and equipment, a system of coordination based upon the
faulted or overloaded circuit is isolated by selective operation of
only the overcurrent protective device closest to the overcurrent
condition.
8
The user should select devices that meet this requirement.

1492-MC Ground Fault Sensing
The Bulletin 1492-MC Circuit Breakers with Ground Fault protection for Branch Circuits are available in 1- and 2-pole construction in
120/240V rating. Versions are available as Ground Fault Circuit Interrupters and as Ground Fault Equipment Protectors.
9
When protection from low-level fault currents for North American standards is required, two versions of protection are available.
ꢀ Circuit Breakers with protection for personnel use a threshold of 5 mA sensing to provide protection for people. These are typically know as
Ground Fault Circuit Interrupters or GFCIs.
ꢀ Circuit Breakers that provide protection for equipment at a sensing threshold of 30 mA are also available. These are typically known as
Ground Fault Equipment Protectors or GFEPs.

The following devices are tested and listed to meet the North American standards of UL 489, UL 943 (for GFCI), UL1053 (for GFEP), and CSA
22.2 No.5.1.
It is recommended that the devices be tested monthly by using the TEST button to check for proper operation of the device.

Product Description
Circuit Breaker Application Information
Application Considerations
Selection of a Bulletin 1489 circuit breaker with appropriate circuit
protection includes consideration of:
The following is a discussion of application considerations related to
North American applications. When applying product to IEC
regional requirements, follow IEC practices and guidelines.
0
1
ꢀ Circuit voltage
The selection of a specific ampere rating for a specific application is
dependent on the type of load and duty cycle and is governed by
the National Electric Code (Canadian Electric Code) and UL/CSA. In
general, the codes require that overcurrent protection is at the
current supply and at points where wire sizes are reduced. In
addition, the codes state that conductors be protected according to
their current carrying capacity. There are specific situations that
require application consideration, such as motor circuit, and
guidelines for the selection for transformer protection.
ꢀ Circuit frequency
ꢀ Available short circuit current
ꢀ Continuous current rating
ꢀ Application considerations
ꢀ Special operating conditions
The following discussion is based upon National Electric Code and
UL requirements. Similar considerations are appropriate for
Canadian applications.
2
The Bulletin 1489-A circuit breakers are “non 100 percent rated” as
defined by UL 489, para 7.1.4.2. As such, the circuit breaker's
rating should be loaded to no more than 80% if used with
continuous loads.
Circuit Voltage
The Bulletin 1489-A circuit breakers are rated by voltage class.
Applications should not exceed the listed voltage and current range
(see Table 1).
3
Line and load may be reversed. The Bulletin 1489 circuit breaker
may be bottom fed.
Branch Circuits:
Circuit Frequency
Bulletin 1489-A circuit breakers may be used to protect branch
circuits. A branch circuit is the wiring portion of a system extending
beyond the final overcurrent device protecting the circuit.
The Bulletin 1489-A circuit breakers may be applied to frequencies
of 50 Hz and 60 Hz without derating. For applications above 60 Hz,
contact Rockwell Automation with specific application information
for the derating of the circuit breakers.
4
Guidelines established in NEC, CEC, UL, and CSA should be used
to determine the specific device. For example:
Available Short Circuit Current
1) Motor Branch Circuit
The Bulletin 1489-A circuit breakers should only be applied in those
applications in which the available short-circuit (or fault) current is
less than or equal to 10 kA...14 kA (US/Canada) and 15 kA (IEC).
5
Bulletin 1489-A circuit breakers are not horsepower rated because
they are able to safely interrupt currents far in excess of the locked
rotor value for a selected motor. This ability is recognized in the
codes and standards and is also established by the UL and CSA
tests described in UL 489 and CSA C22.2 No. 5 standards.

References: NEC 450 and UL 489. Also see CEC and appropriate
Canadian Standards.

3) Heater Load, Lighting, and Other Load Protection
The Bulletin 1489-A circuit breakers are rated in RMS amperes at a
40 °C (104 °F) ambient temperature per the UL 489 (CSA 22.2 No.
5) standard. This temperature is generally used as the average
temperature within an industrial enclosure. If a circuit breaker is
applied in a temperature that exceeds the 40 °C (104 °F) ambient,
then the circuit breaker should be derated. For IEC 60 947-2
standard, the products carry an ambient rating of 30 °C. Follow
standard IEC application considerations for temperature rating in
different ambient temperatures.
Bulletin 1489-A circuit breakers may be used for protection of
heater loads, lighting loads, and other loads following the guidelines
established.
9
References: NEC Article 31 and UL 508A. Also see CEC and
appropriate Canadian Standards.
Coordinated Overcurrent Protection
Where an orderly shutdown is required to minimize the hazards to
personnel and equipment, a system of coordination based upon the
faulted or overloaded circuit is isolated by selective operation of
only the overcurrent protective device closest to the overcurrent
condition. The user should select devices that meet this
requirement.

The characteristic trip curves are shown on page 7-19. The trip
bands shown for each breaker represent current tripping limits for a
circuit breaker and are within the limits established by UL. For a
specific current at 40 °C (104 °F), a circuit breaker will open ("clear
the circuit") automatically at some total time that will be within the
"Minimum" and "Maximum" time shown on the curves. For
example, page 7-19 shows that a one-pole, 15 A, Bulletin 1489-A
circuit breaker trips in not less than 10 s and not more than 120 s
on a 30 A current. Because the UL standard defines this time
spread, users should not specify exact tripping time. The lower
current portion of the curves (upper left) depict the time to trip due
to thermal action and reflect overload protection of the wire and
connect load. The higher current portion of the curves (lower right)
depicts the trip due to magnetic action of the circuit breaker and
reflects protection due to short circuit level currents.

Circuit Breaker
Product Description
HACR Rating
Bulletin 1489-A Ambient Temperature Derating
The standard tripping characteristic for Bulletin 1489-A is Type C.
Type C has a magnetic trip activated at 5…10 times the rated
current of the circuit breaker. The reference temperature for the
thermal tripping characteristics is 40 °C. The Type C characteristic
will suit most applications.
Bulletin 1489-A Circuit Breakers are rated as Heating, Air
Conditioning and Refrigeration circuit breakers as defined by UL
489, paragraph 6.7 and may used in this type of application.
0
SWD Rating
The Bulletin 1489 breakers (0.5 … 20 A) are rated as SWD and as
such may be applied to switch fluorescent lighting loads up to their
current and voltage maximum.
In rare occurrences when the Type C characteristic does not fully
meet the application, the following additional magnetic trip
characteristic is available:
1
Current Limiting
Type D allows for transients approximately twice as high as the
standard Type C.
Bulletin 1489-A Circuit Breakers are rated as current limiting circuit
breakers as defined by UL 489, paragraph 8.6.
Use the following table and graph to determine the current rating for
the breaker if the ambient is significantly different than 40 °C.
2
The Bulletin 1489-A line features the ability to achieve short circuit
interruptions far more effectively than conventional breakers. In
conventional circuit breakers, the short circuit interruption time
required is approximately one or two half cycles of an AC sine wave.
When the contacts open, the resulting arc continues to burn until
the current level passes through zero. The arc may re-ignite
because of the insufficient width of the contact gap. The current
that flows until the arc is extinguished produces a heating effect
proportional to the I2t value (let-through-energy) of the fault current.

Ambient Temperature (°C)
The Bulletin 1489-A device is designed to substantially reduce the
amount of let-through-current and the resulting let-through-energy
that can damage protected components. The Bulletin 1489 has the
ability to interrupt short circuit current within the first half cycle of
the fault. Limiting let-through current and energy will protect against
the harmful effects of overcurrent and is focused primarily on
avoiding the following:

Both of these factors are proportional to the square of the current.
Thermal energy is proportional to the square of the RMS value and
magnetic forces are proportional to the square of the peak value.
The most effective way to provide protection is to substantially limit
let-through-energy. This provides the following advantages

Lock-out Attachment
The 1489-A circuit breaker can function over a wide temperature range
(-30°...+60 °C). Operation in ambient temperatures below 0 °C is based
on a non condensing atmosphere (no ice). Use the graph above or
contact your local Rockwell Automation sales office or Allen-Bradley
distributor to determine the correction factor based upon ambient
temperature.
A sturdy lock-out attachment may be added to a circuit breaker.
This lock-out may be padlocked so that the circuit breaker is locked
in the off position.
5
Shunt Trip
A shunt trip may be added to a circuit breaker to allow the device to
be tripped from a remote source. One version is for tripping
voltages of 12…110V AC (12…60V DC) and another for tripping
voltages of 110…415V AC (110…230V DC).
6
Auxiliary Contacts
An auxiliary contact module may be added to a circuit breaker to
provide pilot duty contacts to indicate the position of circuit breaker,
off or on. This contact changes state when the circuit breaker is
operated either manually or electrically.
7
Signal Contacts
A signal/auxiliary contact module may be added to a circuit breaker
to provide auxiliary contact information off and on and signal
contact pilot duty contacts. With signal contacts, the contacts
change state only when the circuit breaker changes state from On
to Off because of an electrical operation. The module contains one
signal contact, form C contact (N.O. and N.C contact with common)
and one auxiliary contact (N.O. and N.C contact with common).
