Description
The Supco PRO41 Pro Relay Push-On is a solid-state part and overload combination used in refrigeration and compressor starting circuits. It is typically applied in residential refrigerators, freezers, and small cooling systems that use 115V single-phase compressors in the 1/4 to 1/3 HP range in HVAC systems. The unit manages compressor start-up by controlling current flow to the start and run windings while providing overload protection during high current conditions. It operates through a push-on pin terminal connection that interfaces directly with compressor terminals. Placement is on the compressor pin set where it regulates starting torque and protects the motor from overheating during repeated cycling, supporting stable compressor operation.
