{"product_id":"rectorseal-m33246-thermal-time-delay-relay-hvac","title":"Rectorseal m33246 Thermal Time Delay Relay Hvac","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\u003cp\u003eThe RECTORSEAL m33246 is a thermal time delay relay designed for heating and air conditioning control circuits. It operates using a solid state PTC (positive temperature coefficient) device that heats up as current passes through it from the control circuit. That heat causes a snap-acting disc to make or break the necessary contacts, creating a reliable, repeatable time delay without mechanical timers or moving parts. At 0.15 pounds and compact dimensions, this relay fits into tight control panels and equipment enclosures. HVAC technicians install it where sequenced or delayed switching is required in heating and cooling systems.\u003c\/p\u003e\u003cp\u003eThis relay is suited for residential and light commercial HVAC applications where time delay switching is needed in control circuits. Common install scenarios include electric heat sequencing, compressor delay on restart, and fan delay circuits. The PTC-based solid state design requires no adjustment and provides consistent delay characteristics across standard HVAC control voltage applications. It is sold as a single unit and is appropriate for use by licensed HVAC technicians performing control circuit work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid state PTC device provides reliable thermal time delay without mechanical timers\u003c\/li\u003e\n\u003cli\u003eSnap-acting disc contact action ensures positive make or break switching\u003c\/li\u003e\n\u003cli\u003eCompact form factor at 2.8 x 1.7 x 3.6 inches fits standard control enclosures\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.15 pounds for easy handling and installation\u003c\/li\u003e\n\u003cli\u003eSuitable for a variety of heating and air conditioning control circuit applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement thermal time delay relay for residential and light commercial HVAC control circuit applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician. De-energize the control circuit and disconnect power to the equipment before servicing any relay or control component. Follow applicable NEC guidelines for low-voltage control wiring. Verify that the replacement relay matches the electrical requirements of the existing control circuit before restoring power.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Width\u003c\/strong\u003e: 2.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Height\u003c\/strong\u003e: 1.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Depth\u003c\/strong\u003e: 3.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Solid State PTC (Positive Temperature Coefficient)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Action\u003c\/strong\u003e: Snap-acting disc\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: RECTORSEAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: m33246\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RECTORSEAL","offers":[{"title":"Default Title","offer_id":51467640832306,"sku":"M33246","price":25.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945287.png?v=1783909098","url":"https:\/\/voomisupply.com\/products\/rectorseal-m33246-thermal-time-delay-relay-hvac","provider":"Voomi Supply","version":"1.0","type":"link"}
