RDL7-100 Series Residual Current Circuit Breaker RCCB SAA

The item is in comply with standard of IEC61008-1,applying to the circuit of AC50/60Hz,230V single phase400V three phases or below it for industrial and mining enterprisetrade building, commerce and family. lt is mainly used for preventing electric fire and personalcasual accident caused by personal electric shock or leakage of electrified wire net. This is acurrent operated fast leakage protector of pure electromagnetic type, which can break offfault circuit rapidly in order to avoid occurrence of accident. The ltem ls precise in structure,less elements, without auxiliary power and high working reliability. The function of the switchwon’t be influenced by ambient temperature and lightning. The mutual inductor of the item isused to test vector differential value of passing current, and produces a relevant output powerand add it to the tripper In secondary winding, lf the current of vector differential value ofprotected circuit of personal electric shock is up to or over leakage operating current, thetripper will act and cut off so that the ltem will take effect of protection.

Working Principle

                                                   (A)2-POLE                                                                  （B)4-POLE
