4P, 25A, 30mA residual current device CDC425J

The purpose of the residual current device is to protect people, animals and objects in direct or indirect contact with electricity. RCDs also provide fire protection because they monitor the condition of the insulation and disconnect the power supply when leakage currents occur. In the event of an earth fault, when the short-circuit current exceeds the sensitivity of the residual current device, the device automatically switches off the damaged part of the electrical installation within 0.2 seconds. It has an actuation indicator and an optical ON/OFF status indicator. Possibility of adding additional equipment. Ambient temperature from -25 to +40°C.
