Danfoss 117u4127 Relay Overload Combo

Product Description

The DANFOSS 117u4127 is a relay and overload combination component designed for use in refrigeration and HVAC compressor circuits. This type of combo unit integrates a start relay with an overload protector into a single assembly, reducing wiring complexity and simplifying replacement during service calls. It is compact, measuring 1 inch in length, 1 inch in width, and 1 inch in height, and weighs under 0.12 pounds. HVAC and refrigeration technicians install this part as a direct replacement when a failed relay or overload is diagnosed on a hermetic compressor.

Relay and overload combo units like the 117u4127 are commonly used in residential and light commercial refrigeration equipment, including reach-in coolers, refrigerators, and small compressor-based cooling systems. The integrated design allows a single-component swap rather than replacing the relay and overload separately, which speeds up the repair process. This part is suited for applications where the OEM specifies a matched relay and overload assembly.
