It is designed for control circuit switching in HVAC, industrial, and building automation applications where a compact, socketed relay is required. The plug-in terminal type allows for tool-free removal and replacement, making it well suited for panel builds and service scenarios where relay sockets are already mounted. Electricians and controls technicians are the primary installers. Dimensions are 1.9 inches in length, 1.7 inches in width, and 1.3 inches in height, with a weight of 0.16 pounds.\u003c\/p\u003e\n\u003cp\u003eThis relay is used in low-voltage control panels, HVAC equipment control boards, and general-purpose relay socket assemblies in both residential and light commercial settings. Its 4PDT contact form provides four independent switched circuits from a single coil, which is useful for interlock wiring, sequencing, and multi-circuit control logic. The 24 VDC coil makes it compatible with common 24-volt control circuits found throughout HVAC and building automation systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10 amp contact rating at 250 VAC for reliable switching in control circuit applications\u003c\/li\u003e\n  \u003cli\u003e24 VDC coil voltage compatible with standard low-voltage control systems\u003c\/li\u003e\n  \u003cli\u003e4PDT contact form provides four independent switched poles from one coil\u003c\/li\u003e\n  \u003cli\u003ePlug-in terminal type enables fast swap-out without rewiring the socket\u003c\/li\u003e\n  \u003cli\u003eCompact footprint at 1.9 x 1.7 x 1.3 inches fits standard relay socket assemblies\u003c\/li\u003e\n  \u003cli\u003eCE, CSA, UL Recognized, and RoHS Compliant certifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style plug-in replacement relay for use in standard relay sockets accepting 4PDT configurations with a 24 VDC coil and 10 amp contact rating.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician or qualified controls technician. De-energize and lock out the control panel before removing or inserting the relay. Verify that the socket type and pin configuration match the 8501RSD44V53 before seating the relay. Wiring and panel work should conform to applicable NEC requirements for the installation environment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: 24 VDC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Form\u003c\/strong\u003e: 4PDT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTerminal Type\u003c\/strong\u003e: Plug-in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: CE, CSA, UL Recognized, RoHS Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 8501RSD44V53\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51541819162930,"sku":"8501RSD44V53","price":88.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/43c765da2561540fa280ab7ed30bdec9.jpg?v=1785885807","url":"https:\/\/voomisupply.com\/products\/square-d-8501rsd44v53-general-purpose-relay-4pdt-24-vdc","provider":"Voomi Supply","version":"1.0","type":"link"}
