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):
B cure:
– Instantaneous tripping current: 5In
– Instantaneous non-tripping current: 3In
– Application: provides protection to circuits with low inductive load
C curve:
– Instantaneous tripping current: 10In
– Instantaneous non-tripping current:5In
– Application:provides protection to circuits with inductive load or to highly inductive illumination system
D curve:
– Instantaneous tripping current.: 20In
– Instantaneous non-tripping current: 10In
– Application: provides protection to circuits with high inductive load or electric distribution system with high surge current
6.Ambient temperature and current rating curve
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
