ONE-PORT SURGE PROTECTOR FOR
POWER SUPPLY USE
Functions & Features
RELATED PRODUCTS
•Single mount adaptor (model: MBS)
•Wiring bridge (model: CNB)
• Designed to protect electronics equipment from induced
lightning surges entering through power supply cables
• Connected in parallel between the power and
ground lines regardless of load current
GENERAL SPECIFICATIONS
Construction: Plug-in
• Varistor discharge element has a high speed response
without follow current
Degree of protection: IP20 (If the solderless terminals are
covered with insulation tubes.)
• No interruption of power supply even when the head
element is removed: easy maintenance and replacing
• Degraded head element is automatically separated from
the power lines to prevent overheating, with a relay contact
output to alert the failure status
Surge protection type: Voltage limiting type one-port SPD
Connection
Line: M5 screw terminal (spring up-screw type)
(torque: 2.5 N·m)
• Head-base connection is keyed so that only a head
element of correct line voltage can be mounted
Alarm output: Euro type connector terminal
(torque: 0.25 N·m)
Applicable wire size
Typical Applications
Line connection: See the sloderless terminal drawing.
• Low-voltage distribution board
• Combination with installation for large load current
Alarm output: 0.14 to 1.5 mm , stripped length 7 mm
2
Housing material: Flame-resistant resin (black)
Alarm output: The SPDT relay trips when the thermal
breaker operates and/or the head element is removed.
Rated load: 250 V AC @0.5 A (resistive load)
125 V DC @0.2 A (resistive load)
18 ( .71)
Minimum switching load: 5 V DC, 1 mA
97
(3.82)
Line voltage identification key: The connection of the head
element and the base is keyed for exact matching.
Safety function: Thermal breaker incorporated
Failure indicator: The check window color changes from
green (normal) to black (failed and the thermal breaker
separated the M-rester from the circuit).

*1. The circuit breaker must be installed.
Molded-case circuit breakers (MCCB), earth leakage circuit breakers (ELCB) or
current-limiting fuses (slow-blow type only) can be used.

The rated interrupting capacity of the circuit breaker must be greater than the highest
amount of current that could be available in the circuit.
The MCCB or ELCB must has elements at both poles.

*
Circuit
Breaker ‘b’
Time-delay type over-current protection is recommended for an ELCB.
Recommended sensitivity current rating: 30mA

*
*2. If the rated current of the circuit breaker ‘a’ exceeds 30A, or if the loss of power supply
to the protected device should be prevented when the circuit breaker ‘a’ blows due to
a surge protector failure, install the circuit breaker ‘b’ (rated current 20-30 A) at the
branch circuit.
MAKF
*3. Cable length between the branch point and the grounding:
0.5 meters or less recommended.
4
*
Cross-wiring
*4. The protected device’s metal housing must be cross-wired to the ground terminal of
the MAKF. If the protected device has no ground terminal, ground only the MAKF.
*5. In order to protect an electronic circuit such as switching regulartors, we recommend
to use surge protectors which have serial impedance incorporated such as
M-System’s models MAX, MMA, MAH.
Grounding (100Ω or less)

■CONNECTION EXAMPLES BY POWER SYSTEMS
Abnormal voltages appearing in case of a light load or a
ground loop must be within the maximum continuous op-
erational voltage when selecting the MAKF models.
For example, the IEC 60364-5-534 (Electrical installations
of building; devices for protection against overvoltages) re-
quires margins determined by the equations below:

■ALARM OUTPUT
When the alarm output is to be transmitted remotely via
outdoor cables, a surge protector for the signal line is re-
quired.
Choose a circuit breaker with alarm output. Configure a
logical addition sequence so that the alarm trips when both
or either of the MAKF or the breaker alarm trips.
