Fingersafe, spring-up terminals reduce
wiring time.
Ring terminals can be installed as screws are captive.
Retractable Lever
The lever retracts when the circuit breaker is set. As a
result, accidental operation due to bumping the lever, is
prevented. Status of the circuit breaker can easily be
determined by observing the position of the lever.

Conforms to various international
standards
After tripping, the retractable lever is in
the middle position.
Circuit breaker must be turned off before it can be reset.
Distinguishing Characteristics
Wide variety of rated currents and tripping curves.
One and two pole models are AC/DC compatible
and allow for a reduction in inventory.
Rated Short-circuit Capacity 2500A
Available with Inertia Delay
Safe Trip-free Mechanism
Allows for use with large inrush currents such as
motors and lamps.
The circuit remains open even when the operator is turned
on after tripping (unit must be manually reset after
removing the cause of the tripping).

Note 1: 3-pole type is for AC voltage only.
Note 2: For S (instantaneous) tripping curve, humming sound may occur when used in an AC sinusoidal-wave current circuit around 80% of the
rated current, however, the performance of the circuit breaker will not be affected.
To avoid unnecessary tripping, do not use in circuits where inrush currents may be present.
Note 3: Relay trip (voltage trip) type is not equipped with an overcurrent trip function.
•
Do not use the NC1V circuit breakers in environments where they are exposed to extreme temperature, humidity, dust, corrosive gases,
vibration, shock, or in a circuit where inrush current may be present, otherwise unnecessary operation and damage may occur.
