Hard Start Kit, 500% Torque Increase, 90/277V

The Supco Relay/Capacitor Hard Start Kit boosts starting torque and improves compressor reliability in HVAC and refrigeration systems.

Designed for PSC (Permanent Split Capacitor) type compressors, this prewired hard start kit combines a potential relay with a start capacitor to enhance startup performance. It operates across a wide 90–277 VAC range, reducing light dimming, lowering startup stress, and extending compressor life.

• Voltage rating: 90–277 VAC, ensuring broad system compatibility.
• Compatible with PSC type compressors in HVAC and refrigeration applications.
• Prewired assembly with integrated relay and start capacitor simplifies installation.
