It operates on a 120 VAC coil at 50\/60 Hz and supports motor loads up to 1\/2 hp at 120 volts or 3\/4 hp at 240 volts. The plug-in design allows for quick socket-based installation and field replacement without rewiring. Electricians and controls technicians use this relay in industrial control panels, HVAC equipment, and general-purpose switching applications where a compact, socketed relay is required.\u003c\/p\u003e\u003cp\u003eThis relay is suited for light commercial and industrial control circuits where reliable electromechanical switching is needed. Common applications include motor control, panel automation, and load switching in HVAC systems, machinery, and building automation equipment. The 4PDT contact form provides four independent switching circuits from a single coil, making it versatile for complex control logic in a compact footprint.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10 amp contact rating at 250 VAC for robust switching capacity\u003c\/li\u003e\n\u003cli\u003e4PDT contact form provides four independent circuits per energization\u003c\/li\u003e\n\u003cli\u003e120 VAC coil at 50\/60 Hz for compatibility with standard North American and international control voltage\u003c\/li\u003e\n\u003cli\u003eMotor load rating of 1\/2 hp at 120 volts and 3\/4 hp at 240 volts\u003c\/li\u003e\n\u003cli\u003ePlug-in terminal type enables fast socket installation and replacement\u003c\/li\u003e\n\u003cli\u003eMeets CE, CSA, RoHS, and UL Recognized standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style plug-in replacement relay for general purpose control panel and HVAC applications requiring a 4PDT, 120 VAC coil relay in a standard socketed footprint.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician or qualified controls technician in accordance with applicable NEC requirements. De-energize the control panel and verify zero voltage at the socket before inserting or removing the relay. Ensure the relay socket matches the 8501RS44V20 pin configuration before installation. Do not exceed the rated contact current or motor load ratings.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Form\u003c\/strong\u003e: 4PDT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Rating\u003c\/strong\u003e: 10 amps at 250 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Voltage\u003c\/strong\u003e: 120 VAC at 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Load Rating\u003c\/strong\u003e: 1\/2 hp at 120 volts, 3\/4 hp at 240 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Type\u003c\/strong\u003e: Plug-in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards Met\u003c\/strong\u003e: CE, CSA, RoHS Compliant, UL Recognized\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SQUARE D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8501RS44V20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51542914629938,"sku":"8501RS44V20","price":88.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/562f23dece6670fe635f974d0d9c0328_a3c2db67-506f-428b-a043-a0629fdeb918.jpg?v=1785910808","url":"https:\/\/voomisupply.com\/products\/square-d-8501rs44v20-general-purpose-relay-10a-4pdt","provider":"Voomi Supply","version":"1.0","type":"link"}
