DZ47S-63 Circuit Breaker

Scope of Application DZ47S-63 Miniature Circuit Breaker with shunt trip is suitable for AC 50Hz (or 60Hz), rated voltage 230 / 400V, rated current 63A of the line, remote control and automatic signal breaking control for the line, is mainly used for over-load and short-circuit protection in circuits. And infrequent transfer between circuits in normal condition. Currently widely used in IC card prepaid watt-hour meter to control on-off of lines. DZ47-60 Circuit Breaker has a small size, easy installation, etc., controls residential charged meter, when the IC card recharge balance is insufficient, the control circuit breaker will automatically disconnect to play the role of power outages, and users can close the circuit after recharging. Main functions: overload protection, short circuit protection, isolation, accept the IC card power meter signal to cut off the circuit. DZ47S-63 Miniature Circuit Breakers meet standards of IEC60898, GB10963, GB14048.2, with the international advanced level.
