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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eStart relay with 1\/4 inch spade connectors for fast, secure field connections\u003c\/li\u003e\n\u003cli\u003eDesigned for single-phase hermetic compressor applications in refrigeration and HVAC systems\u003c\/li\u003e\n\u003cli\u003eOEM-quality Danfoss component for reliable compressor startup and motor protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Danfoss 117U4151 start relay delivers dependable compressor startup performance with convenient 1\/4 inch spade connector terminations.
