A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by an overcurrent or short circuit. Its basic function is to interrupt current flow to protect equipment and to prevent the risk of fire. 

Features:

1. The Chint Circuit Breaker is high quality!
2. Residual current operating characteristics AC type, A-type
3. The rated residual operating current IΔn (ma) (2p, 3P+N, 4P) is not adjustable in a single gear,
4. and it is 50/100/200/300/500/1000 without delay
5. (2P, 3P+N, 4P) the single gear is not adjustable, delay type 50/100/200/300/500/1000
6. The rated residual inoperative current IΔno (ma) is 0.5IΔn.
7. Maximum breaking time (s) of non-delay 5IΔn ≤ 0.04
8. The main function of the residual current operated circuit breaker series is to provide indirect contact
9. protection for fatal personal electric shock, and to provide protection for electrical fire caused by
10. ground-fault current, such as insulation damage. It also provides protection for overload, short
11. circuit and Undervoltage of the line, and can also be used for infrequent switching of the line.
12. Grade of shell frame: 125A, 160A, 250A, 400A, 630A, 800A
13. The rated working voltage Ue(AC): AC 230V/240V(1P+N, 2P),
14. AC 400V/415V(3P, 3P+N,4P）
15. Code of breaking capacity: s and h
16. Number of poles: 1P+N, 2P, 3P, 3P+N, 4P 1P+N, 2P is only applicable to shell products of 250A and below)
17. Installation mode: fixed type and plug-in type
