The air switch, that is, the air switch, can quickly cut off the circuit and provide reliable protection when the circuit is connected, disconnected, and carries the rated working current, short circuit, overload and other fault currents, and when the line and load are overloaded, short-circuited, or undervoltage. There are many designs of dynamic and static electric shock rods for circuit breakers. The purpose of distribution boxes is to improve the breaking capacity of circuit breakers. Nowadays, using the principle of contact to control the current of the open circuit has been widely used, and has obvious effects.
Automatic air switch, also known as low-voltage circuit breaker, can be used to open and close the load circuit, and can also be used to control the infrequent starting of the motor. It is a component that integrates the functions of circuit breakers, overcurrent relays, voltage loss relays, thermal relays and leakage protectors. It is also a device for protecting low-voltage distribution networks.
