Emerson Climate-White Rodgers 90-342 PWR/PWR Relay 2 DPDT 240V

The Emerson Climate-White Rodgers 90-342 PWR/PWR Relay 2 DPDT 240V is an electrically operated switch that controls a circuit using a low-power signal to switch on a high-power circuit in HVAC systems. Designed with a coil that produces a magnetic field when it is supplied with current, and this causes a set of contacts to close or open depending on the type of relay. This makes or breaks the circuit, enabling the controlled system to turn on or off. In systems, switches are used to switch on or off different loads like compressors, motors, or heating elements.
