The main structure of the contactor
The service life of the contactor is very high, the mechanical life is usually several million to ten million times, and the electrical life is generally several hundred thousand to several million times.
The contactor can operate at high frequencies, up to 1200 times per hour when the power is turned on and off.
20A above the contactor with an arc extinguishing cover, the use of the circuit when the electromagnetic force generated by breaking, quickly pull off the arc, the protection of contacts
The other half is the activities of the core, structure and fixed iron core, to drive the main contacts and auxiliary contacts closed off.
