AC contactor operation power source

AC solenoids, Air circuit breaker two "mountain" shape the young quartet built silicon, one fixed, put coils in the above, the operating voltage has a variety to choose from. To make magnetic stability, the core of the pull side, coupled with short-circuit loop. AC contactor in the loss of power, relying on spring return. The other half is the active core, structure and the fixed core to drive mcb circuit breaker contacts and auxiliary contacts open short. More than 20 amps interrupter contacts plus a hood, disconnect the circuit using the electromagnetic force generated, quickly pull off the arc, to protect the contacts. AC contactor production as a whole, appearance and performance is improving, but the function remains unchanged. Whether and to what extent the development of electric meter, common AC contactor still has its importance. AC contactor breaking widely used as power and control circuits. AC contactors use the main contact to open and close the circuit, with auxiliary contacts to execute control commands. Generally only the main contacts normally open contacts, and often two pairs of auxiliary contacts with normally open and normally closed contacts function, small contacts are often used as intermediate relay with the main circuit.
