Description
The ABB AF30-30-00-11 3-Pole Contactor is an electromechanical switching element that is used in HVAC systems to control the power of motors and compressors and other high-current loads in response to a 20-60 VDC managed signal. It operates in sets of contacts that open or close together to complete or break power circuits to coordinate the switching of large electric elements. This offers a better isolation & load control option within the HVAC systems to facilitate sequenced operation of significant equipment.
