NBSM30-125 Series MCB AC 2P 100A 230/400V Industrial Circuit Breaker, thermal breaker
The NBSM1-125 Industrial breaker is our new design with patent, characterized by compact design, light weight, elegant appearance, high breaking capacity, swift releasing, long service life, Different handle color for different rated current, with contactor condition indicator.
The NBSM1-125 is applied in the power system of AC 50Hz, rated voltage up to 400V and rated current up to 400A, for power distribution and protecting Power system from overload, short circuit, faults damage etc. it also can be used to control infrequent operation.
The rated residual operating current In and the maximum breaking time can be adjusted on site according to practical condition.
The leakage protection module still can work normally when the phase voltage reduce to 50V. It has the same overall size with the UKM30L series circuit breakers, which make the installation more exchangeable.
The circuit breakers comply with the demands of the IEC60947 standards.
