Contactor is an electrical component that serves to connect or disconnect electrical current to the AC. Contactor or in other words we can find relay contactor on the electric control panel. In electrical panels the contactor is often used as a selector or transfer switch and interlock on the ATS system. The function of contactors is generally used to disconnect and connect electric current electrically. Usually used for applications: motor, heater, lighting or electric power distribution. The working principle of a contactor is like a relay, in a contactor there are several electromagnetic-controlled switches.
Product Details :
Contactors are available for 1 phase and 3 phase. And in general the contactor used is 3 phases.
This 1-phase contactor basically has a coil (coil), main terminal, auxiliary contact (not installed as an addition as in the 3 phase). There are also contactors that do not have an auxiliary contact. The structure is very simple because only one main terminal is open-close.
This 3 phase contactor basically has a device such as a 1 phase contactor, only playing the terminal has 3 pieces. In addition the auxiliary contact can be added by attaching it to the contactor.
