Air switch, also known as air circuit breaker, is a type of circuit breaker. It is a switch that will automatically open as long as the current in the circuit exceeds the rated current. The air switch is a very important electrical appliance in the low-voltage distribution network and electric drive system. It integrates control and multiple protection functions. In addition to completing contact and breaking circuits, it can also protect short circuits, severe overloads and undervoltages in circuits or electrical equipment. It can also be used to start motors infrequently.
Main function: Under normal circumstances, the armature of the overcurrent release is released; once a serious overload or short circuit fault occurs, the coil in series with the main circuit will produce strong electromagnetic attraction. Attract the armature downward to open the locking hook and disconnect the main contact.
The undervoltage release works exactly the opposite. When the voltage is normal, the electromagnetic attraction attracts the armature and the main contact can be closed. Once the voltage drops severely or the power is cut off, the armature is released and the main contact is disconnected. When the power supply voltage returns to normal, it must be re-closed before it can work, thus achieving voltage loss protection.
