Fireproof plastic mcb 3phase 100 amp mcb electric circuit breaker curve D
Application
GZ47-100 series Miniature Circuit Breakers has small size, light weight, novel structure and excellent performance. The material of enclosure and inside plastically parts is fire resistance and withstand shocking.
It is used in lighting distribution system or motor distribution system for protecting overload and short-circuit in the system.The product is novel in structure,light in weight,reliable and excellent in performance.It has high breaking capacity,can trip quickly and its installation uses with guide, its case and items are adopted with high fire-resistant and shockproof plastics.
The product,with long life,is mainly used in AC 50Hz/60Hz single-pole 240V or two,three,four-pole 415V circuit for overload and short-circuit protection as well as for unfrequent on-and-off switching electric equipment and lighting circuit in normal case.
This product comply with GB10963,IEC898,BS3871.

Special Tips
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):
