Danfoss 117U4060 120V Compressor Starting Device

The Danfoss 117U4060 is a 120-volt starting device designed for hermetic compressor applications in refrigeration and air conditioning systems. This solid-state starting relay provides reliable motor starting assistance for single-phase compressors, eliminating the need for traditional electromechanical start relays.

Key Features:

• 120V AC operation for standard residential and commercial applications
• Solid-state design for improved reliability and longer service life
• PTC (Positive Temperature Coefficient) thermistor technology
• Compact housing for easy installation in tight spaces
• No moving parts to wear out or fail
• Universal mounting capability with quick-connect terminals

This starting device works by temporarily providing additional starting torque to the compressor motor during startup, then automatically removing itself from the circuit once the motor reaches operating speed. The PTC technology ensures consistent performance across a wide range of ambient temperatures and operating conditions, making it ideal for refrigerators, freezers, air conditioners, and other hermetic compressor applications.
