Danfoss 117u7020 Compressor Relay 312-155D

Product Description

The DANFOSS 117u7020 is a compressor relay designed for use with the 312-155D compressor. The relay provides the start signal necessary to initiate compressor motor operation, engaging the start winding briefly at startup before dropping out once the motor reaches running speed. This type of relay is a common service replacement in light commercial refrigeration systems and is installed by refrigeration technicians as part of a compressor service or replacement procedure. The unit is compact, measuring 1.001 inches on each side, and weighs 0.08 pounds.

This relay is suited for light commercial refrigeration applications where the 312-155D compressor is installed. It is referenced under the Beverage Air part number 314-075D, indicating use in Beverage Air refrigeration equipment. Technicians servicing reach-in coolers, back-bar units, or similar light commercial refrigeration equipment will encounter this relay as a replacement component during compressor or electrical service calls.

Installation Notes

Compressor relay replacement should be performed by a qualified refrigeration technician. Disconnect power to the unit before accessing the compressor compartment and handling any electrical components. Relays must be oriented correctly per compressor terminal identification — verify terminal layout before installing. Inspect the compressor start and run capacitors as part of the same service call, as these components often fail together.
