Supco SPP8E E Series Electronic Potential Relay Hard Start Kit for 1+ HP Compressors

The Supco SPP8E E Series Electronic Potential Relay Hard Start Kit is designed to provide reliable starting assistance for single-phase compressor motors rated at greater than 1 horsepower. This solid-state hard start device uses electronic potential relay technology to deliver consistent performance and extended service life compared to traditional electromechanical relays.

Key Features:

• Electronic potential relay design eliminates mechanical contacts for improved reliability
• Suitable for compressor motors greater than 1 HP
• Compatible with 189-227 MFD start capacitor range
• Solid-state construction provides longer service life than mechanical relays
• Helps reduce inrush current and compressor starting stress
• Universal mounting bracket for easy installation
• Ideal for HVAC/R applications including air conditioners, heat pumps, and refrigeration systems

Hard start kits are essential for compressors operating in challenging conditions such as low voltage situations, high ambient temperatures, or systems with long refrigerant line sets. The SPP8E provides the starting torque boost needed to get the compressor running smoothly while protecting against motor damage from repeated start attempts.
