Description
AC 4P 63A MCB TOMC3-63 has elegant appearance; curved cover and handles make operation comfortable with a contact position indication window. It is designed with a transparent cover for the label. When an overload occurs, in order to protect the circuit, the MCB handle trips and stays in the center position, which can make the fault line fast solution. The handle cannot stay in this position during manual operation. MCB handle can be locked in “ON” position or “OFF” position to prevent unnecessary operation of the product
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
