The difference between MCB and MCCB

1, circuit breaker can access the coarse wire, such as more than 35 square. Small circuit breakers are only suitable for the following 10 square meters of wire.

2, circuit breaker end for nut connection, easy compression, good contact. Small circuit breakers with a smaller clamping terminal, and can only be tightened with a screwdriver, torque is not enough, it is not easy to press, contact is not good.

3, the circuit breaker over-current and short-circuit protection device are respectively used two sets, over-current protection action value can be manually adjusted. Small circuit breaker on the flow and short circuit sharing a device, the current can not be adjusted.

Large distance 4, MCCB and white, and the arc shield, arcing ability is strong, can withstand greater short-circuit currents, it is not easy to cause short. Long life.

5, a small circuit breaker MCCB with high sensitivity ratio.
