25KA MCB 240V Circuit Breaker 1 Pole with High Breaking Capacity

 

 

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.

The over-current tripping unit protection feature

 

International Standard--- IEC 60898-1 and European Standard EN 60898-1 define the rated current In of a circuit breaker for low voltage distribution applications as the maximum current that the breaker is designed to carry continuously (at an ambient air temperature of 30 °C). The commonly-available preferred values for the rated current are 20 A, 25 A, 32 A, 40 A, 50 A, 63 A, 80 A, 100 A, and 125 A (Renard series, slightly modified to include current limit of British BS 1363 sockets). The circuit breaker is labeled with the rated current in amperes, but without the unit symbol "A". Instead, the ampere figure is preceded by a letter "B", "C" or "D", which indicates the instantaneous tripping current — that is, the minimum value of current that causes the circuit breaker to trip without intentional time delay (i.e., in less than 100 ms), expressed in terms of In:
