Supco 90380 General Purpose Fan Relay Spdt 24V Coil

Product Description

The SUPCO 90380 is a general purpose fan relay designed to receive and control electrical signals in HVAC and refrigeration fan circuits. Part of the SUPCO 902 series, this relay features SPDT contact configuration with both normally open and normally closed positions, giving installers flexible switching options. Contacts are constructed from silver alloy for reliable conductivity and long service life. The coil operates at 24VAC and is compatible with multiple coil voltage ratings across the range. With a 13-amp load rating and a sealed enclosure, the 90380 suits a wide range of light commercial and residential fan control applications.

This relay is used in HVAC and refrigeration systems where fan motor circuits require independent control through a low-voltage signal. It is commonly installed in air handling units, condensing units, and refrigeration cases where a control board or thermostat output switches the relay coil to energize or de-energize a fan motor. The sealed enclosure protects internal contacts from contaminants in mechanical rooms and equipment cabinets. HVAC technicians and refrigeration service professionals are the primary installers of this component.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician. De-energize and lock out all power to the unit before removing or installing the relay. Verify coil voltage matches the control circuit output before wiring. Follow applicable NEC requirements for low-voltage control wiring and line-voltage load connections.
