Product Description
Low-voltage air circuit breaker, also known as automatic air switch or air switch, is a switching device. It is used to automatically break the circuit when the circuit is overloaded, short-circuited, or under-voltage. It can also be used to start the motor or switch the circuit infrequently. , Low-voltage air circuit breakers include universal circuit breakers, molded case circuit breakers, miniature circuit breakers, leakage circuit breakers and so on. 1. The structure of low-voltage circuit breaker:
1. The main contact connects or disconnects the main circuit. When the switch is closed manually or electrically, the main contact is closed, and the main contact is disconnected when the circuit is short-circuited, overloaded, or undervoltage.
2. Free trip mechanism:
The function of the free trip mechanism is to lock the main contact in the closing position after the main contact is closed, and the release is unlocked when the protection mechanism is activated.
3 Arc extinguishing system, when the main contact is disconnected, the iron grid in the fire extinguishing chamber will induce strong magnetism. Attract the arc into the grid and burn it in sections to protect the contacts from damage.
