Supco URCO410 3-in-1 Hard Start Relay Overload & Capacitor 1/4-1/3 HP 115V

The Supco URCO410 is a universal 3-in-1 solid-state hard start kit that combines a relay, overload protector, and start capacitor into a single, compact module. Designed as a direct replacement for aging or failed refrigeration compressor starting components, this all-in-one unit simplifies servicing and restores reliable compressor operation.

When the compressor needs to start, the capacitor delivers a high-torque boost of electrical energy to the start winding, overcoming inertia and locked rotor conditions. Once the motor reaches operating speed, the solid-state relay disconnects the start winding, allowing the motor to run on its main winding. The integrated overload protector continuously monitors current draw and disconnects power if a fault or excessive load is detected, protecting the compressor from damage.
