Supco RCO220 Relay Capacitor Overload Hard Start Kit

Description

The Supco RCO220 is a 3-in-1 Relay Capacitor Overload (RCO) hard start kit engineered to improve compressor starting performance in residential and light commercial HVAC and refrigeration systems. By combining a start relay, start capacitor, and overload protector into a single, easy-to-install assembly, the RCO220 dramatically reduces compressor start-up time and amp draw — helping extend the life of your compressor and protecting it from damaging overload conditions.

This all-in-one solution is ideal for service technicians looking to restore or upgrade compressor starting capability without the need to source multiple individual components. The RCO220 is designed for universal compatibility across a wide range of single-phase hermetic compressors found in air conditioners, heat pumps, and refrigeration equipment.

Key Features

• 3-in-1 design: integrates start relay, start capacitor, and overload protector
• Boosts compressor starting torque for reliable start-up under low-voltage or high-load conditions
• Reduces locked rotor amp (LRA) draw during start-up
• Protects compressor motor windings from overload and thermal damage
• Designed for universal fit on single-phase hermetic compressors
• Simplifies service calls — one part replaces three separate components
• Compact, plug-in design for fast, straightforward installation

Applications

• Residential and light commercial air conditioners
• Heat pumps
• Refrigeration equipment with single-phase hermetic compressors
