Class I 10/350 Iimp 2p Single Phase AC 220V Power Surge Protector

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.

Power supply protector, also known as air circuit breaker, is a kind of circuit breaker. It is a switch that will automatically disconnect as long as the current in the circuit exceeds the rated current. Power protector is a very important electrical appliance in low-voltage distribution network and electric drive system, which integrates control and multiple protection functions. In addition to completing the contact and breaking circuit, it can also protect the circuit or electrical equipment from short circuit, serious overload and undervoltage, and can also be used to start the motor infrequently.
