Operating at 230 volts, it combines a starting relay and overload protector into a single assembly, reducing component count and simplifying service calls. Licensed HVAC and refrigeration technicians install this type of combination component when replacing failed starting components on fractional and small hermetic compressor units. The integrated design ensures proper coordination between the start-assist function and the thermal overload protection.\u003c\/p\u003e\u003cp\u003eThis combination relay and overload is suited for residential and light commercial refrigeration applications, including reach-in coolers, window air conditioners, and similar equipment that uses single-phase hermetic compressors rated at 230 volts. The PRO Series designation indicates this unit is intended for professional service use. Technicians working on compressor startability issues or replacing burnt-out overloads will find this a direct-fit solution where the pro42 is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCombination design integrates starting relay and thermal overload in one assembly\u003c\/li\u003e\n\u003cli\u003eRated for 230-volt single-phase hermetic compressor applications\u003c\/li\u003e\n\u003cli\u003eReduces service time by replacing two components with a single unit\u003c\/li\u003e\n\u003cli\u003ePRO Series construction suited for professional refrigeration and HVAC service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement combination relay and overload for 230-volt single-phase hermetic compressors in residential and light commercial refrigeration and air conditioning equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC or refrigeration technician. Disconnect and lock out all power to the unit before removing the existing relay and overload assembly. Verify the replacement part number against the compressor nameplate and original component before installation. Follow applicable NEC and local electrical codes when servicing refrigeration and air conditioning equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 230 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: PRO Series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Combination Relay and Overload\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Single-Phase Hermetic Compressor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SUPCO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: pro42\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUPCO","offers":[{"title":"Default Title","offer_id":51138757656882,"sku":"PRO42","price":16.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7610bb0779e1669212e32b94f68478d9_6e997ad3-92c8-4e55-b0fd-4c8d9187af68.jpg?v=1778263098","url":"https:\/\/voomisupply.com\/products\/supco-pro42-relay-with-overload-combination-230v","provider":"Voomi Supply","version":"1.0","type":"link"}
