This earth leakage circuit breaker from Eaton Moeller’s PKNM series has a total of 2 poles, one of which is protected (1p+n). In addition, the ground fault circuit breaker has a double comfort terminal lift/window and a free choice comb rail position below and above. The color of the switch lever indicates the rated current. Furthermore, this earth leakage circuit breaker has limited impact resistance and plus current sensitivity. This type of the Eaton Moeller PKNM earth leakage circuit breakers protects DC fault currents at special non-flattened shapes. The rated voltage is 230V and the rated current is 20A.
