Commercial Automatic Miniature Circuit Breaker Electrical MCB 6000A

 

 

Description:

 

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike afuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.

 

 

Advantages:

1)DZ47 series MCB is used in lighting distribution system or motor distribution system for protecting overload and short circuit in the systems.


2)This product is novel in structure, light in weight, reliable and excellent in performance.


3)It has high breaking capacity and can trip quickly. Its case and body are made of highly fire-retardant and shockproof plastic.


4)This 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 infrequent on-and-off switching electric equipment and lighting circuit in normal cases. This product conforms to GB10963 and IEC60898 standards.
