The product used in the video is an ABB AF series contactor with a pilot light rated for 120 VAC. The coil voltage is also rated for 120 VAC. The front mount auxiliary contact has an external power supply to demonstrate a normally closed contact function. The pilot lights are rated for 24 VDC. A contactor can stand on its own as a power control device, or as part of a starter. Contactors are used in applications ranging from a light switch to the most complex, automated industrial equipment. Contactors are used by electrical equipment that is frequently turned off and on (opening and closing the circuit), such as lights, heaters and motors. The function of the contactor is always the same; to make and break all power supply lines running to a Load or, as defined by NEMA, to repeatedly establish and interrupt an electrical power circuit.
