The Supco RCO410 is a premium solid-state 3-in-1 hard start kit meticulously engineered to assist residential and commercial refrigeration compressors. Combining a heavy-duty start capacitor, solid-state relay, and thermal overload protection into a single pre-wired package, this module provides the vital electrical torque boost required to kick-start sluggish or older compressor units under low-voltage conditions.
Designed for 115V single-phase systems, this kit features a high capacitance range of 243 to 292 MFD and handles up to a 6.8A maximum continuous run-load amperage. HVAC technicians and maintenance professionals rely on this components kit to permanently bypass failing factory relays or overloads, restoring rapid compressor initialization and preventing premature motor failure without requiring full compressor replacements.
When diagnosing refrigeration issues, matching the correct horsepower rating and system voltage is critical for proper operation. This hard start kit is suitable for a wide array of capillary-based refrigeration and air conditioning systems. Prior to installation, verify your compressor operates within the designated 1/4 to 1/3 HP specifications and review manufacturer wiring schematics.
