Contractor
The contactor is a type of switch that works magnetically ie the contact works when the coil is energized. The National Manufacture Association (NEMA) defines magnetic contactor as a magnetically driven device for connecting and unlocking electrical power. Unlike relays, contactors are designed to connect and unlock power circuits without damage. These loads include lamps, heaters, transformers, capacitors, and electric motors. We also provide Relays and Electrical Contactors.
