DZ47 Mcb Mini Circuit Breaker
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.
Product advantages:
1. completely independent intellectual property right,national utility model patent.
2. The overall is nice with sleek and smooth line.
3. It is easy to distinguish with different colors of different
specifications.
4. It is comfortable to operate with embowed handles.
5. It is flexible to install and dismantle with creative design clips.
6. Setting oblate direction ,more beauty and more standard.
7. To meet customers needs with more connection styles.
8. Enhancing the ability of reflex arc when short circuit breaking
with many improvements.
9. Enhancing the ability of extinction arc when short- circuit breaking with many improvements.
10. Short-circuit breaking capacity (ICS) of products get to 6KA combining many improvement.
