What is an Air Switch
An air switch, also known as an air circuit breaker, is a type of circuit breaker. It is a switch that automatically opens when the current in the circuit exceeds the rated current. Air switches are an essential electrical appliance in low-voltage distribution networks and power drive systems, combining control with various protective functions. In addition to completing the connection and disconnection of circuits, they also provide protection against short circuits, severe overloads, and under-voltage conditions in circuits or electrical equipment. They can also be used for infrequent motor starting.
