Danfoss 117u4151 Start Relay 1/4 Inches Spade Connector

Product Description

The Danfoss 117U4151 is a start relay designed for use in refrigeration and HVAC compressor applications. Start relays are critical components in single-phase hermetic compressor systems. They provide the temporary boost needed to get the compressor motor running from a dead stop. Once the motor reaches operating speed, the relay disconnects the start winding from the circuit. This protects the motor and ensures efficient ongoing operation. The Danfoss 117U4151 features 1/4 inch spade connectors for fast, secure electrical connections during installation and service work. Spade terminals are a standard connection type widely used in refrigeration controls, making field replacement straightforward for HVAC technicians and refrigeration mechanics. Danfoss is a globally recognized manufacturer of refrigeration and HVAC controls, known for producing reliable, precision-engineered components for commercial and residential systems. Their start relays are built to meet the demands of professional trade applications, including walk-in coolers, refrigerators, freezers, and air conditioning units. Replacing a faulty start relay is one of the most common service tasks on single-phase compressor systems. Symptoms of a failed start relay include the compressor clicking and not starting, tripping on thermal overload, or drawing excessive current at startup. Using a manufacturer-matched relay like the Danfoss 117U4151 ensures compatibility with the compressor's electrical specifications. This part is suited for HVAC technicians, refrigeration service contractors, and equipment maintenance professionals who need a dependable OEM-quality replacement relay. The 1/4 inch spade connector design allows for tool-free terminal connections, reducing installation time on service calls.
