DZ20LE leakage circuit breaker DZ20LE-160/4300 DZ20LE-250/4300 DZ20LE-400/4300 DZ20LE-630/4300 DZ20L series leakage circuit breakers for AC 380V, frequency 50Hz, rated current of 600A and below the circuit can be carried out on the line overload, short circuit, and undervoltage protection, may be used as infrequent line conversion purposes. Residual operating characteristics of this series leakage circuit breakers for AC-type performance standards GB14048.2GB6829 standards. The main difference between the equivalent of molded case circuit breaker shell electric current at different current specifications can shell frame, not the same range of the rated current.
