Description
The IDEC Relays RH3B-ULAC240V Blade Relay W/Indicator is an electromechanical control relay designed with a 240-volt AC coil, a 3 PDT (Three-Pole Double-Throw) contact arrangement, and a built-in indicator for visual status monitoring. It is used to switch multiple electrical circuits in response to a control signal while providing a clear indication of relay activation. In HVAC systems, it is commonly installed in control panels, air handling units, and equipment control circuits where coordinated operation of motors, contactors, and auxiliary controls is required. The relay manages signal routing and electrical switching between control components and connected equipment.
