Supco SPP6 Super Boost Hard Start Kit for Air Conditioners and Heat Pumps

The Supco SPP6 Super Boost Hard Start Kit is designed to solve hard starting compressor problems in residential and commercial air conditioning units and heat pump systems. This kit increases starting torque by 500%, reducing stress on the compressor during startup and extending system life.

Key Features:

• Positive Temperature Coefficient (PTC) relay combined with start capacitor
• Capacitance range of 130-156 microfarads
• Easy 2-wire installation across run capacitor terminals
• Designed for use on permanent split capacitor single phase A/C and heat pump systems
• Compatible with 1/2 to 10 HP compressors (4,000 to 120,000 BTU)
• UL Recognized and NATE Recognized
• Voltage range: 90-277 VAC

This hard start kit is ideal for addressing low voltage conditions, aging compressors, or systems that experience difficulty starting. The PTC relay automatically disconnects the start capacitor after the compressor reaches operating speed, providing reliable performance without additional controls.
