The air switch is also a miniature circuit breaker, which is used to turn on, break and carry rated working current in the circuit, and can be used in the case of overload, short circuit and undervoltage of the circuit and motor

For reliable protection. The moving and static contacts and the contact rod of the circuit breaker are designed to be parallel, and the moving and static contacts are disconnected by using the electric repulsive force generated by short circuit, which has high breaking ability and special current limiting

Strong sex.

In short circuit, the aromatic insulation around the static contact is vaporized, which plays the role of cooling and arc extinguishing, and the arc flying distance is zero. The arc extinguishing chamber of the circuit breaker adopts metal grid structure, and the contact system has

Repulsive current limiting mechanism, therefore, the circuit breaker has high breaking ability and current limiting ability... with compound release. The inverse time action is that the bimetal sheet is bent by heat to make the release act

The instantaneous action is the action of the release driven by the iron core street iron mechanism. There are three tripping modes: thermal tripping, electromagnetic tripping and compound tripping.
