The Chint Circuit Breaker is high quality!
Residual current operating characteristics AC type, A type
The rated residual operating current IΔn (ma) (2p, 3P+N, 4P) is not adjustable in single gear,
and it is 50/100/200/300/500/1000 without delay
(2P, 3P+N, 4P) single gear is not adjustable, delay type 50/100/200/300/500/1000
The rated residual inoperative current IΔno (ma) is 0.5IΔn.
Maximum breaking time (s) of non-delay 5IΔn ≤ 0.04
The main function of residual current operated circuit breaker series is to provide indirect contact
protection for fatal personal electric shock, and to provide protection for electrical fire caused by
ground fault current, such as insulation damage. It also provides protection for overload, short
circuit and undervoltage of the line, and can also be used for infrequent switching of the line.
