A brief introduction to the power contactor
20 amp or more contactor with an arc extinguishing cover, the use of breaking the circuit when the electromagnetic force generated, quickly pull off the arc to protect the contacts.
The AC contactor relies on a spring return after power failure. The other half is the activities of the core, the structure and fixed iron core, to drive the main contacts and auxiliary joints of the short
one of the fixed, put on the coil above, the working voltage has a variety of options. In order to stabilize the magnetic force, the suction surface of the core, plus the short circuit ring
AC contactor action power from the AC electromagnet, electromagnet by the two "mountain" shaped silicon steel sheet stacked
