Rheem-Ruud 42-25104-06 SPDT NO/NC Relay 24V

The Rheem-Ruud 42-25104-06 Relay is an electric control component that switches the circuit in accordance with the low-voltage control signals in HVAC systems. It has a single-pole, double-throw contact arrangement with both normally open and normally closed loads and can use 24 volts to direct power between two circuits when operated in air handlers and furnaces. It is fitted in the control panel and connected between the source of control and the loads it controls. When the coil is switched, internal contacts also switch to either complete or interrupt circuits in the coordinated operation of the system.
