MCCB Molded Case Circuit Breaker

GYCM3, GYCM3L, and GYCM3E series circuit breakers are a new updated product produced with the benefits of similar international products and consumer demand from both domestic and international markets. This series has a rated insulation voltage of up to 1000V and is ideal for power distribution networks with AC 50Hz. It has a rated voltage of 400V (690V) and a rated current of 800A and is used to transmit electrical energy and protect circuit power equipment from overload, short circuit, under-voltage, and other faults. At the same time, it serves as the motor’s infrequent start, overload, short circuit, and under-voltage safety. The circuit breaker is small in size, has a high breaking capacity, and a short flying arc. It can be mounted vertically or horizontally.

GEYA MCCB complies with all standards and regulations including iec60947-2, GB/T14048.2.
