It is designed for control circuit applications in HVAC, refrigeration, and light commercial equipment where reliable low-voltage switching is required. The relay features a Class B insulation system and a double make contact configuration, providing both normally open and normally closed switching options in a single unit. Licensed HVAC technicians and controls specialists are the primary installers of this relay in field wiring and OEM panel assemblies.\u003c\/p\u003e\u003cp\u003eThis relay is suited for residential and light commercial HVAC control boards, fan relay panels, and general purpose switching enclosures. Its multi-positional mounting design allows flexible installation in a variety of panel orientations. The 0.250-inch quick-connect terminals simplify field wiring connections. Where space or panel layout is a constraint, the compact form factor and mounting flexibility make it a practical choice for retrofit and new-construction control panel work alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e24 VAC coil voltage for standard low-voltage control circuit compatibility\u003c\/li\u003e\n\u003cli\u003eSPDT switching with 1 NO and 1 NC contact configuration\u003c\/li\u003e\n\u003cli\u003eDouble make contact design for reliable circuit switching\u003c\/li\u003e\n\u003cli\u003eClass B insulation system for thermal durability in control environments\u003c\/li\u003e\n\u003cli\u003e0.250-inch quick-connect (QC) terminals for fast field termination\u003c\/li\u003e\n\u003cli\u003eMulti-positional mounting for flexible panel installation\u003c\/li\u003e\n\u003cli\u003eUL 508 listed (File No. E227250, Class NLDX2 and DNLDX8)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general purpose switching relay for use in HVAC control panels, relay boards, and light commercial control enclosures requiring 24 VAC SPDT relay functions.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified controls electrician. De-energize and lock out the control panel before removing or installing the relay. Verify that the supply voltage matches the 24 VAC coil rating before energizing. Wiring should comply with NEC low-voltage control circuit requirements and any applicable local codes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Voltage\u003c\/strong\u003e: 24 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitching Configuration\u003c\/strong\u003e: SPDT (1 NO, 1 NC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Configuration\u003c\/strong\u003e: Double make\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Type\u003c\/strong\u003e: 0.250-inch quick-connect (QC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Class\u003c\/strong\u003e: Class B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: Multi-positional\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eListing\u003c\/strong\u003e: UL 508, File No. E227250, Class NLDX2 and DNLDX8\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: HARTLAND CONTROLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: tp-90370\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARTLAND CONTROLS","offers":[{"title":"Default Title","offer_id":51383051649330,"sku":"TP-90370","price":24.51,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312675039.webp?v=1782586654","url":"https:\/\/voomisupply.com\/products\/hartland-controls-tp-90370-24-vac-spdt-general-purpose-relay","provider":"Voomi Supply","version":"1.0","type":"link"}
