General
The UL recognized component mark on the MCB means that the
component alone meets the requirements for a limited, specific use. These
MCBs are not intended for separate installation in the field, they are
intended for use as a component of complete equipment submitted for
investigation to UL.
The UL Listed mark on the MCB is the manufacturer’s representation that
samples of the complete product have been tested by UL to be used for
most common industrial applications. This superior UL mark allows for field
installation without the need for UL investigation.

D-TRIP
ONE POLE
ONE POLE PLUS NEUTRAL
CHARACTERISTICS
Application Examples:
High inrush motors, transformers,
power supplies, heaters and reactive
loads. Relatively long thermal trip
delay and very high magnetic trip
point.
Prototype testing is recommended in
motor applications where the relatively
long thermal trip delay may not
provide adequate motor overload
protection. Motor-integral overload
protectors are recommended, with the
V-EA-D providing disconnect, backup
thermal protection and additional short
circuit and energy let-through
protection.

Application Examples:
High efficiency motors, which have
exceedingly high inrush currents.
Relatively short thermal trip delays

Prototype testing is recommended.
The V-EA-E is the result of continuous

combines the short thermal trip delay
of the G-Trip and an even higher
magnetic trip point than the D-Trip.

Voltage drops should be reviewed when
V-EAs with high internal resistance are
used (e.g., load voltage minimums).
Power loss should be reviewed when
V-EAs with high rated currents are used
(e.g., enclosure heating).
The listed V-EA internal resistance values
should not be used in calculations of
available short-circuit current downstream
of the V-EA. The dynamic impedance of
the V-EA under short-circuit conditions
can vary significantly from internal
resistance values in normal operation.

LINE CURRENT FREQUENCY EFFECTS ON TRIP CURVES
The thermal trip is not affected by the frequency of the line
current. The magnetic trip is within the trip zone of the
characteristic curve for frequencies from 16 2/3 to 60Hz. At
lower and higher frequencies, the magnetic trip will be delayed
longer than indicated by the characteristic curve, roughly as
follows:

At DC:
Mag. Trip Current = 1.5 x curve current
For example, at 16 2/3 - 60 Hz the magnetic trip zone for the “G”
characteristic is 8 to 10 times the rated current of the specific
V-EA (i.e., hold for at least 100ms at 8 x RC, trip in less than
100ms at 10 x RC). With a 400Hz current, a magnetic trip at 10
x RC would be greatly delayed (thermal would likely trip first), as
the magnetic trip zone is now 11.2 to 14 x RC. If a quicker
magnetic trip is required with 400Hz, the “B” or “C” characteristic
should be considered.

INSTALLATION RECOMMENDATIONS
INTRODUCTION
EASY REMOVAL
The V-EA* easily snaps onto a readily available, international
standard 35mm DIN Rail. Mounting can be in any position from
full horizontal to full vertical without affecting performance.
Removal, One Pole
1. Insert tip of 4mm or less straight blade screwdriver into the
slot of the metal retaining clip.
All housings are the same size regardless of rated current,
simplifying layout and modifications.
2. Brace the shank of the screwdriver against the terminal
side of the V-EA* and gently lever the clip away from the
DIN rail.
Line power feed can be to either top or bottom terminals. This
provides flexibility to power distribution enclosure entry (top,
bottom, sides) and internal raceway runs (e.g., power in one
horizontal raceway can feed both the row above and the row
below).
3. When the clip moves out, continue rotating screwdriver
and V-EA* up and off of the bottom of the DIN rail lip.
4. Grasp V-EA* and lift upwards to disengage from the top
lip of the rail, then remove.
Minimal free space is required to remove or replace the V-EAs,
and with standard housing and terminal sizes, ratings can be
changed or multi-poles can replace multi-single pole or vice-
versa. To obtain the highest density mounting arrangement
without serious problems from heat build-up, see “Temperature
Correction Curve” (page 22).
Altech and our distributors are pleased to quote custom rail
assemblies. Multi-function assemblies can include cut-to-order
DIN Rail, mounted V-EA and MA circuit breakers, FI Earth
Leakage breakers, lightning/surge protectors, interface modules
(cable fan-out, relays, I/O, power supply, etc.), terminal blocks
with marking tags, and other control components to meet your
specifications. Order assemblies with only one part number or
even your drawing number.
DIN Rail Information
Mounting rails are internationally standardized and are available
in several sizes with or without perforations. Zinc-plated yellow
chromated steel is standard. Copper and aluminum DIN Rails
are also available. Please contact Altech for your DIN Rail
needs.

ALTECH/SPELSBERG EK/AK NONMETALLIC ENCLOSURES FOR MCBS
NOTE 1: For totally enclosing the V-EA, the
minimum interior depth of the enclosure is
70mm plus DIN Rail depth (7.5 or 15mm) plus
any rail mounting stand-off depth.
NOTE 2: Fork lugs with a thickness up to
3mm can be inserted in the lower terminals
under the head of the captive M5 (i.e. 5mm
diameter to outside of threads) terminal screw.
NOTE 3A: The V-EA’s raised face is sized to
fit through standard European enclosure cut-
outs, which allow sight and operation of the
trip/reset handle but keep all wiring covered.
As shown in Fig. 1, Altech/Spelsberg AK/EK
nonmetallic enclosures are ready-made for
this attractive and efficient packaging ap-
proach.
NOTE 3B: The V-EA was successfully short-
circuit tested in TYPE 1 metal enclosures with
the V-EA face extending through a 46mm cut-
out in the cover. Typical applications include:
• V-EA on 35mm wide by 15mm deep DIN
Rail, mounted to back wall of a 3 inch deep
enclosure with no back panel.
• V-EA on 35mm wide by 7.5mm deep DIN
Rail, mounted to the back panel of a 3 inch
deep enclosure with panel.

An IEC device with excellent ratings under a
UL listing at 480Y/277V (including group
ratings) and at 500V under international
standards, the Altech/ Sursum MA provides
short and long term cost effective circuit
protection for USA and/or export
applications. The short term advantages
include: (1) adjustable thermal trip allows
finalization of initial designs before
procurement of the load equipment is
complete; (2) snap-on mounting for readily
available, internationally standardized DIN
Rail saves panel layout design time as well
as installation and change labor; (3) large
cage-clamp terminals with screws suitable to
power screwdrivers, simplifies and speeds
wiring; (4) convenient switched disconnect
during factory testing and/or initial start-up
saves time and aggravation. The key long
term advantage is customer satisfaction and
proven over-current protection of wiring and
equipment (and the lack of rework/repair
costs).

FI EARTH LEAKAGE
CIRCUIT BREAKERS
FI compact Earth Leakage Circuit
Breakers detect and interrupt earth
(ground) faults. They are VDE
approved for the European system
of protecting people, animals,
equipment and property from
dangerous line-to-ground and shock
hazard currents.
US applications include ground-fault
protection of equipment (GFPE)
using the 10mA and 30mA fault
current ratings, especially when high
distributed capacitance or other
leakages cause excessive nuisance
trips at lower fault currents.
Applications for the 300mA rating are
equipment protection and fire
prevention, limiting the energy of a
fault to less than the minimum
ignition energy for many materials.

15g with impact force half-cycle sinusoidal and 11ms duration, 18 impacts total with 6 on each principal axis
(3 impacts each face). FI is DIN Rail mounted during the test, and electrically loaded with 25% of Fault RC.
Successful testing required no trip during the test, no damage and no loosened parts.
Impact/Shock Protection
5g, at frequency of 55Hz to 2,000Hz, applied for 35 ± 5 minutes along each of the three principal axes, plus
5 minutes of application at every established critical resonant frequency. FI is DIN Rail mounted during the
test, and loaded with 25% Fault RC. To pass, the FI did not trip at 25% Fault RC, but did trip between each
of the principal axis tests when the fault current was raised to 125% Fault RC, and there was no damage
and no loosened parts. Suitable for machinery and mobile vehicle applications.
Vibration/Seismic Resistance
Ingress Protection (IP) Class 40; internal working components and live parts (excluding terminals) are
protected against ingress of solid objects greater than 1mm diameter (class 4-), but have no protection from
ingress of water (class-0).

Coil actuated, the FA Shunt Trip allows
electrical remote tripping of a breaker. It
is trip-free and the housing and terminal
specifications are the same as for V-EA
miniature circuit breakers.The Shunt Trip
contains its own contacts which break
the tripping power circuit when tripped. It
is available with trip-coils in most
standard control voltages. The device is
UL and CSA listed for general use.
Re-power your system under controlled
conditions following a power loss or
serious undervoltage. Altech/Sursum UA
Undervoltage Trips are coupled to the
tripping latch pins of the V-EA or MA to
which they are attached, reliably produc-
ing trips at the drop-out voltage and
preventing resetting when less than 85%
line voltage is present. The Undervoltage
Trip is provided with at least 6-inch
pigtails of stranded fixture wire for hook-
up to the V-EA or MA line terminals.
• Reset-Hold Voltage = 0.85 x Ve
• Drop-Out Voltage = 0.35 to 0.7 x Ve

Touch protection
Cat. No. 15.962 (top) and 15.961 (bottom)
The V-EA protects against electrical shock
during manual actuation in accordance with
VDE 0106/Part 100 and VDE 0470/Part 1,
with “finger safe” terminal-screw heads and
“back of hand” safe terminals. If additional
“touch” protection is desired, separate touch
protector covers can easily be snapped on to
the V-EA top and/or bottom terminals.
