AC Relay for HVAC and Industrial Switching – HCR Series by Hartland Controls/Littlefuse
Hartland Controls’ relays provide power system on/off switching capabilities. The primary purpose of Hartland Controls/Littelfuse’s relays is to switch electrical circuits on and off in an instant. Relays are essentially electromagnetic switches activated by a low power signal or current in one circuit to open or close another circuit. They are most commonly used in power system networks and multiple automotive and industrial applications or HVAC where the system is controlled by 24 VAC, 120 VAC, or 240 VAC.
