Description
The IDEC Relays RR3B-ULAC24V Power Relay is an electromechanical switching component designed to manage multiple electrical circuits using a 24 VAC coil input with a 10A contact rating. It is installed in control panels, air handling units, and furnace assemblies where it routes electrical signals between thermostats, controllers, and fan or compressor circuits. Within HVAC systems, it is an interface component that enables controlled switching between multiple electrical paths through an electromagnetic coil that activates three independent contact sets. This operation supports organized signal distribution and circuit coordination across connected equipment.
