TOC2XN-4 4P 1NO 1NC 2NO 2NC AC Contactor

4p contactor is rated according to the design load current, maximum fault withstand current, and design life expectancy of each contact.


4P Contactor

The 4P Contactor is an electrically controlled switch used for switching an electrical power circuit, similar to a relay except with higher current ratings and a few other differences.

Contactor is controlled by a circuit which has a much lower power level than the switched circuit.

Contactor come in many forms with varying capacities and features. Unlike a circuit breaker, a contactor is not intended to interrupt a short circuit current.

Contactors range from those having a breaking current of several amperes to thousands of amperes and 24 V DC to many kilovolts.

The physical size of contactors ranges from a device small enough to pick up with one hand, to large devices approximately a meter on a side.

Contactors are used to control electric motors, lighting, heating, capacitor banks, thermal evaporators, and other electrical loads.
