Rated for 3.5 to 5 HP compressors operating at 208, 230, or 265 volts single phase, this kit uses a mechanical potential relay rather than circuit boards, timers, or PTCR devices. The mechanical relay design reduces failure points and eliminates solid-state components that can degrade over time. Licensed HVAC technicians and refrigeration mechanics install this kit as a compressor starting aid in both new installations and service calls.\u003c\/p\u003e\u003cp\u003eThe tp-ks1 applies to single-phase air conditioning, refrigeration, and heat pump compressors in the 3.5 to 5 HP range. It is suited for residential and light commercial systems where low voltage conditions, high head pressures, or weak utility power make compressor starting unreliable. The pre-assembled design simplifies field installation, making it a practical solution during service calls where time on-site is limited. It has received product approval from compressor and equipment manufacturers, confirming its fit across a range of single-phase compressor applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwo-wire connection — no additional wiring runs or control boards required\u003c\/li\u003e\n\u003cli\u003eMechanical potential relay design eliminates circuit boards, timers, and PTCR devices\u003c\/li\u003e\n\u003cli\u003eRated for 3.5 to 5 HP single-phase compressors at 208, 230, and 265 volts\u003c\/li\u003e\n\u003cli\u003ePre-assembled from the factory for fast field installation\u003c\/li\u003e\n\u003cli\u003eAssists compressor starting under adverse conditions including low voltage and high head pressure\u003c\/li\u003e\n\u003cli\u003eApproved by leading compressor and equipment manufacturers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for single-phase air conditioning, refrigeration, and heat pump compressors rated between 3.5 and 5 HP operating at 208, 230, or 265 volts single phase.\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 beginning work. Connect the two wires from the tp-ks1 to the compressor start and run terminals per the wiring diagram on the kit. Verify voltage and HP ratings match the compressor nameplate before energizing the system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 208, 230, and 265 volts single phase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompressor Size\u003c\/strong\u003e: 3.5 to 5 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelay Type\u003c\/strong\u003e: Mechanical potential relay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring Configuration\u003c\/strong\u003e: Two-wire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: Single phase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number (Alt)\u003c\/strong\u003e: 97330\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TRADEPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: tp-ks1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRADEPRO","offers":[{"title":"Default Title","offer_id":51383960633650,"sku":"TP-KS1","price":78.25,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312674204.webp?v=1782613273","url":"https:\/\/voomisupply.com\/products\/tradepro-tp-ks1-hard-start-kit-3-5-5-hp-208-230v","provider":"Voomi Supply","version":"1.0","type":"link"}
