SDEV Charger
1 / 2
DZ47LE-63 Residual Current Circuit Breaker RCD is available in 1P+N, 2P, 3P, 3P+N, and 4P configurations. It supports rated voltages of 230V and 400V with residual current sensitivity options including 30mA, 50mA, 100mA, and 300mA.
1. Application
DZ47LE-63 is applicable to lines of AC 50Hz/60Hz, rated voltage 230V for single pole two-wire, 2-pole or 400V for 3-pole, 3-pole 4-wire, 4-pole and rated current up to 40A. It can protect the line and motor from overload and short circuit. It can also be used for infrequent line conversion and infrequent motor start. It conforms with the standards of IEC61009.
