Designed for control circuit switching in industrial and commercial applications, this relay handles up to 1-1\/2 horsepower and carries a 10 VA power rating. Contacts are rated at 40 amps at 277 VAC and 5 amps at 600 V, making it suitable for a range of load types. The screw clamp terminal design provides secure, vibration-resistant connections. Electricians and controls technicians install this relay in panel assemblies, motor control circuits, and automated switching systems where reliable DPDT switching is required.\u003c\/p\u003e\u003cp\u003eThis relay is suited for use in residential, commercial, and light industrial control panels. It fits standard DIN-rail or panel-mount enclosures and is commonly installed in HVAC control systems, motor starters, and building automation panels. The compact footprint — 2.6 inches wide, 2.5 inches high, and 3.2 inches deep — makes it practical for dense panel layouts where space is limited. Licensed electricians typically handle installation in line-voltage or mixed-voltage control applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDPDT contact form supports two independent switched circuits from a single coil\u003c\/li\u003e\n\u003cli\u003e12 VDC coil voltage for low-voltage control circuit integration\u003c\/li\u003e\n\u003cli\u003eScrew clamp terminals for secure, tool-assisted wire termination\u003c\/li\u003e\n\u003cli\u003eContact rating of 40 amps at 277 VAC and 5 amps at 600 V\u003c\/li\u003e\n\u003cli\u003eRoHS compliant and UL Listed (File E78351); CSA certified (File 218139 Class 3211 04); meets IEC 60947-4-1\u003c\/li\u003e\n\u003cli\u003eCompact dimensions suit high-density panel installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement general purpose relay for use in standard industrial and commercial control panel assemblies requiring a DPDT, 12 VDC coil relay with screw clamp termination.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out all circuits before handling or replacing the relay. Verify coil voltage supply matches the 12 VDC rating before energizing. Screw clamp terminals require a flathead or terminal screwdriver for proper torque; do not over-tighten terminal screws beyond the hardware manufacturer guidance marked on the device.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Voltage\u003c\/strong\u003e: 12 VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Form\u003c\/strong\u003e: DPDT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Rating\u003c\/strong\u003e: 1-1\/2 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Rating\u003c\/strong\u003e: 10 VA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Rating\u003c\/strong\u003e: 40 amps at 277 VAC; 5 amps at 600 V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Type\u003c\/strong\u003e: Screw Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 3.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.49 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: UL Listed File E78351; CSA File 218139 Class 3211 04; IEC 60947-4-1; RoHS Compliant\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: 8501CDO16V51\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51543356506418,"sku":"8501CDO16V51","price":173.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c7e843b8c3ad9f34bb3b4490dc1f2a39_1d68a960-92d1-45ad-9269-ba89917aa6a2.jpg?v=1785916997","url":"https:\/\/voomisupply.com\/products\/square-d-8501cdo16v51-general-purpose-relay-dpdt-12-vdc","provider":"Voomi Supply","version":"1.0","type":"link"}
