The AC contactor uses the main contact to open and close the circuit, and the auxiliary contact to conduct the control loop. The main contact generally only has a normally open contact, while the auxiliary contact often has two pairs of contacts with normally open and normally closed functions. Small contactors are often used as intermediate relays in conjunction with the main circuit. The contacts of the AC contactor are made of silver-tungsten alloy, which has good electrical conductivity and high temperature ablation resistance.

The action power of the AC contactor comes from the AC electromagnet. The electromagnet is made of two "mountain" shaped young silicon steel sheets stacked up. One of them is fixed, and a coil is placed on it. There are many working voltages to choose from. In order to stabilize the magnetic force, a short-circuit ring is added to the attraction surface of the iron core. After the AC contactor loses power, it relies on spring return. The other half is the movable iron core, which has the same structure as the fixed iron core and is used to drive the switch of the main contact and auxiliary contact.

Contactors above 20 amps are equipped with an arc extinguishing cover, which uses the electromagnetic force generated when the circuit is disconnected to quickly break the arc to protect the contacts. The contactor can perform high-frequency power on and off control, and the maximum operating frequency can even reach 1,200 times per hour. The contactor has a very long service life. The mechanical life is usually millions to ten million times, and the current life is generally hundreds of thousands to millions of times.

WCT Din Rail Mounted Contactor Details

Scope of Application

WCT Din Rail Mounted Contactor (also called CT contactor, household Contactor), mainly used in power system of AC 50Hz/60Hz, rated voltage to 400V, rated current to 100A, at AC-1, AC-7a use categories (no sense or low sense load, resistance furnace, household appliances and similar low load) for long distance, switch and control circuit for household, can also be used to control the motor load. Household Contactor is not used for breaking short circuit current, so the suitable short-circuit protection equipment (such as miniature circuit breaker) should be selected when using. It meets the standard IEC61095, GB17885.

WCT Din Rail Mounted Contactor can extend auxiliary control, protection and indication function.

Product Features
