Wholesale VCM1 6A to ***0A 1P 2P 3P 4P Molded Case Circuit Breaker MCCB Price



General Introduction

 

Function

VCM1 series MCCB applies to AC *0HZ, rated insulation voltage up to **0V(VCM***3 only up to **0V), working voltage up to **0V(VCM***3 only up to **0V), rated current up to ***0A, functions as non frequently switching in a circuit and non frequently starting a motor. MCCB is mainly used in a building power distribution system, protection against short-circuit, overload and under voltage, as well as non frequently switching. MCCB can be classified into L(standard), M(medium) and H(high) according to its lcu.

 

Further, neutral line and phase line can be opened and closed simultaneously to avoid the high potential transmission, which could ensure the safety the operator. In addition to the protection in circuit and motor, other protection and control functions can be realized by installing under voltage relay, shunt relay, alarm contact and electrical mechanism.
