iCT DIN Rail Modular Contactor is a kind of control electric appliance which is used for long distance/remote switch on and break off a non-inductive load or low inductive load, such as electric resistance furnace, household appliances and similar low inductive load,motor and other household application.
Contactors are divided into AC contactors (voltage AC) and DC contactors (voltage DC), which are used in power, power distribution and power consumption. Broadly speaking, contactor refers to an electrical appliance that uses the current flowing through the coil to generate a magnetic field and close the contact in order to control the load. main features The AC contactor uses the main contact to open and close the circuit and the auxiliary contact to turn on the control circuit. The main contact is generally normally open contact, while the auxiliary contact often has two pairs of normally open contact and normally closed contact. Small contactors are often used as intermediate relays to cooperate with the main circuit. The contact of AC contactor is made of silver tungsten alloy, which has good conductivity and high temperature ablation resistance. The power of AC contactor action comes from the magnetic field generated by AC through the coil with iron core. The electromagnet core is composed of two "mountain" shaped young silicon steel sheets. One of the fixed iron core is sleeved with coil, and the working voltage can be selected. In order to stabilize the magnetic force, a short-circuit ring is added to the suction surface of the iron core. After the AC contactor loses power, it returns by spring. The other half is a movable iron core, whose structure is the same as that of a fixed iron core, which is used to drive the closing and breaking of the main contact and auxiliary contact.
