Hot sale Energy Voltage Power Lightning Surge Protectors

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.

The tripping mechanism of the switch is a set of connecting rod devices. When the main contact is closed through the operating mechanism, it will be locked in the closing position by the locking hook. If there is a fault in the circuit, the relevant release will act to release the locking hook in the release mechanism, and the main contact will quickly break under the action of the release spring. According to the different protection functions, the release can be divided into over-current release and voltage-loss release.
