Description
The Schneider Electric (Square D) RUMC21F7 Relay is an electromechanical switching component used to control electrical circuits in heating and cooling equipment. Operating with a 120 VAC coil and rated for circuits up to 250 volts it enables a low-power control signal to switch higher-power loads. Commonly applied in control panels, automation assemblies, and equipment controls the relay manage the operation of motors, contactors, and other electrical components. Used throughout HVAC systems, it supports coordinated circuit control by opening or closing electrical connections in response to system commands.
