The Chint Circuit Breaker is high quality!
The rated working voltage Ue(V), AC 50/60Hz 230/240,400/415
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 is of non-delay type 30/50/100/200/300/500
(2P, 3P+N, 4P) single gear is not adjustable, and the delay type is 50/100/200/300/500
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.
