Low Voltage 4p SPD Surge Protective Device Power Surge Protector

When testing whether the power supply protector is normal, professional personnel should be invited to use the leakage phase detector to test. If the power supply protector is in the normal protection state, the power supply protector of each circuit will trip separately, and the leakage protector will also trip together. If the power supply protector is in an abnormal state, only the main switch trips, the separate power supply protector does not trip, and the leakage protector does not trip.

The most important feature of the wiring behind the board is that the circuit breaker can be replaced or repaired without having to re-wire, just disconnect the previous power supply. Due to the special structure, the product has been equipped with special mounting plate, mounting screws and connecting screws according to the design requirements when leaving the factory. It is necessary to pay special attention to the fact that the reliability of the contact of the large-capacity circuit breaker will directly affect the normal use of the circuit breaker. Therefore, attention must be paid to the installation and the installation must be carried out strictly according to the manufacturer's requirements.
