POWER CONTACTOR -L& t, SCHNEIDER, DELIXI A contactor is an electrically controlled switch used for switching an electrical power circuit. A contactor is typically controlled by a circuit which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch. contactor is an electrically controlled switching device, designed for repeatedly opening and closing a circuit. Contactors tend to be used for higher current-carrying applications than standard relays, which do a similar job with low current switching. Advantages: Suitable for high power applications: Contactors are designed to control high power electrical currents, making them suitable for applications such as HVAC systems, lighting systems and electric motor systems. #CONTACTOR #SPARKELECTRIC
