3P Industrial Type Circuit Breaker Type D Mcb NBSM30-125 Series Din Rail Installation
NBSM30-125 Series MCB AC 3P 100A 230/400V Industrial Circuit Breaker, type d mcb
Description:
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 circuit breaker can protect people against indirect contact with dangerous electric current and prevent fire disaster caused by insulation fault and single-phase ground fault.It can be used to distribute electric power and protect power equipment against overload and short circuit.The circuit breaker can change the circuit and start motor infrequently.
The rated residual operating current and the maximum off-time can be adjusted on-site according to actual situation,the circuit breaker can be customized alarm function and no tripping
