White-rodgers 90-380 Fan Relay 24V Spno/spnc

Product Description

The WHITE-RODGERS 90-380 is a heavy-duty general purpose fan relay designed to operate in any mounting position, making it a versatile choice for HVAC control circuits. It features a 24 VAC coil rated for 50/60 Hz operation and a Class B insulation system, with a continuous duty cycle suitable for sustained control applications. The relay provides both SPNO and SPNC switch action, allowing flexibility in low-voltage fan control wiring. Coil terminations are 1/4-inch quick connect, and the coil operates at 85 percent of nominal coil voltage with a maximum safe operating voltage of 110 percent of nominal. Licensed HVAC technicians and controls specialists are the primary installers of this relay.

The 90-380 is part of the 90-360 through 90-486 relay family and is suited for residential and light commercial HVAC applications where a dependable 24-volt fan relay is required. Typical installations include forced-air furnace fan circuits, air handler controls, and general HVAC low-voltage control boards where a switching relay is called for. Its any-position mounting capability simplifies placement in tight equipment cabinets or control panels.
