Utica-Dunkirk R49 Relay 10A 110/120VAC

The Utica-Dunkirk R49 Relay is an electromechanical switching component used to control circuits within heating equipment. It responds to incoming control signals by opening or closing contacts, allowing connected components to operate according to the system's programmed sequence. Rated for 10A and 110/120 VAC operation, it is an interface between control circuitry and electrical loads that require signal-based activation. Used in HVAC systems, it supports the coordination of operational and automated equipment responses. It is installed during maintenance or repair procedures to restore circuit switching and control performance.
