It provides a controlled on-delay of 1 to 20 seconds and an off-delay of 40 to 110 seconds on switch M1-M2, preventing simultaneous element energization that would otherwise spike current draw and trip breakers. The unit is UL component recognized and is rated for ambient operating temperatures from -50 to 165 degrees F, making it suitable for both standard and harsh-environment installations. Licensed HVAC technicians are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThe 24a34-001s1 is used in electric furnaces, electric air handlers, and heat-strip assemblies where sequenced staging of resistance heating elements is required. It is rated at 14.0 amps FLA and 72.0 amps LRA at 120 Vac, and 7.0 amps FLA and 42.0 amps LRA at 240 Vac, covering the voltage ranges most common in residential electric heat applications. The 480 Vac rating at 12.5 amps also supports light-commercial heat-strip configurations. It serves as a direct replacement for most fan and heat sequencing functions in systems requiring a single-switch sequencer.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-switch (M1-M2) design with on-delay of 1 to 20 seconds and off-delay of 40 to 110 seconds\u003c\/li\u003e\n  \u003cli\u003eMulti-voltage rating: 120 Vac, 240 Vac, and 480 Vac operation supported\u003c\/li\u003e\n  \u003cli\u003eResistive load ratings up to 3000W at 120 Vac and 6000W at 240 Vac or 480 Vac\u003c\/li\u003e\n  \u003cli\u003eVA output of 125 VA at 120-240 Vac and 480 VA at 480 Vac\u003c\/li\u003e\n  \u003cli\u003eWide ambient operating range: -50 to 165 degrees F\u003c\/li\u003e\n  \u003cli\u003eUL component recognized for code-compliant installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the 24A34 Series Electric Heat Sequencers product family.

Always disconnect and lock out all electrical power to the air handler or electric furnace before removing or installing the sequencer. Verify that the replacement unit voltage and amperage ratings match the existing system requirements before wiring. Follow all applicable NEC guidelines for line-voltage component replacement in electric heating equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Count\u003c\/strong\u003e: 1 (M1-M2)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOn Timing (M1-M2)\u003c\/strong\u003e: 1 to 20 seconds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOff Timing (M1-M2)\u003c\/strong\u003e: 40 to 110 seconds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage at 120 Vac\u003c\/strong\u003e: 14.0 FLA, 72.0 LRA, 25.0 amps, 3000W Resistive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage at 240 Vac\u003c\/strong\u003e: 7.0 FLA, 42.0 LRA, 25.0 amps, 6000W Resistive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage at 480 Vac\u003c\/strong\u003e: 12.5 amps, 6000W Resistive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVA Output\u003c\/strong\u003e: 125 VA at 120-240 Vac; 480 VA at 480 Vac\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmbient Operating Temperature\u003c\/strong\u003e: -50 to 165 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.57 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL Component Recognized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Mexico\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: WHITE-RODGERS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 24a34-001s1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WHITE-RODGERS","offers":[{"title":"Default Title","offer_id":51138331771186,"sku":"24A34-001S1","price":41.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305534036.png?v=1778253623","url":"https:\/\/voomisupply.com\/products\/white-rodgers-24a34-001s1-electric-heat-sequencer","provider":"Voomi Supply","version":"1.0","type":"link"}
