Danfoss 7701154 CSR Starting Kit 25+25+140 MFD

Description

The Danfoss 7701154 CSR Starting Kit is a complete capacitor start/run hard-start solution engineered to dramatically improve compressor starting torque in residential and light commercial HVAC and refrigeration systems. By combining run and start capacitor values in a single, convenient kit, this assembly reduces startup amp draw, minimizes compressor wear, and extends equipment service life — particularly in systems that experience low-voltage conditions or frequent cycling.

Product Overview

This CSR kit delivers a proven three-component capacitor configuration rated at 25+25+140 MFD, providing both the run capacitance needed for steady-state motor operation and the high-value start capacitance required to overcome inertia at startup. It is designed as a drop-in hard-start upgrade for single-phase compressors across a wide range of HVAC/R equipment.

Key Features

• Complete CSR (Capacitor Start/Run) hard-start kit in a single package
• Capacitor configuration: 25 MFD run + 25 MFD run + 140 MFD start
• Engineered to boost compressor starting torque and reduce startup current draw
• Helps protect compressors operating under low-voltage or high-load conditions
• Reduces mechanical stress on compressor windings and motor components
• Extends compressor service life and reduces nuisance trip-outs
• Designed for straightforward field installation
• Danfoss quality engineering for dependable, long-term reliability

Applications

• Single-phase residential and light commercial air conditioning compressors
• Refrigeration compressors experiencing hard-start conditions
• Systems subject to low-voltage supply or long line sets
• Retrofit hard-start upgrades on aging HVAC/R equipment

Why Choose a CSR Hard-Start Kit?

Compressors are among the most expensive components in any HVAC/R system. Hard-start conditions — caused by low voltage, high back pressure, or worn components — place extreme stress on compressor windings and can lead to premature failure. The Danfoss 7701154 CSR Starting Kit provides the extra starting torque needed to get the compressor spinning quickly and efficiently, protecting your investment and keeping systems running at peak performance.
