AC 3P 63A MCB TOMC3-63 provides isolation and protection for AC systems. Also, it is available in different breaking capacities, tripping curves and current ratings. This product is compatible for loads like motor, air conditioner etc. This is a 3P, 63A MCB with a breaking capacity of 3kA.DZ47-63 series miniature arcut breaker (hereinafter rferedto as cirauit breaker) is a curert limiting high-breaking miniature circuit breaker with overload and short-arcut protecton,.tis suitable for the cirouit ofAC 50/60Hz. rated woring voltage up to 400V, rated working current 63A and below, to protect the aircut against the over load and short circut. The product complies with GB10963 and IEC60898-1 standard.

1. MCB is for non-professional operation by those untrained, and no maintenance is required
2. Satisfying conditions and applications as mentioned above,MCB with “ON-OFF” indicating device is considered suitable for isolation function.
3. Particular devices such as surge protective devices,surge arrester etc are recommended to install at upstream line to MCB as precaution against potential surge voltage and current occurring at its power input side.
4. Appropriate tripping curve being chosen and properly installed, MCB trips and switches off its protected circuit in case of fault, and thus provides protection against electric shock.
5. B,C,D tripping curve(see graphics 1):

1.Protection against both overload and short circuit

2.Contact position indication

3.Applicable to terminal and pin/fork type Busbar connection

4.Easy mounting onto 35mm DIN rail
