This sequencer controls the order and timing in which electric heating elements are energized, helping to prevent voltage sags, tripped breakers, and excessive demand loads that occur when multiple high-draw elements activate at the same instant. The 24a55-1 features two main switches and one auxiliary switch, giving HVAC technicians the flexibility to manage multiple heating stages and auxiliary functions from a single, reliable component. Electric heat sequencers like the 24a55-1 are a critical part of any staged electric heating system. When a thermostat calls for heat, the sequencer receives a low-voltage signal and then uses a bimetal element or resistance heater to time the activation of each heating stage. This staged startup reduces inrush current, protects the electrical supply, and extends the service life of heating elements and contactors. The 24a55-1 is sold as an individual unit and is compatible with a wide range of electric furnaces and heat pump air handlers that use sequencer-based staging. HVAC technicians, heating contractors, and electrical service professionals rely on this type of sequencer for both new installations and replacement service work. Whether you are troubleshooting a no-heat call, replacing a failed sequencer, or building out a staged electric heat system, the Copeland 24a55-1 delivers consistent, repeatable switching performance. It is a direct-fit solution for systems requiring two main switch contacts and one auxiliary switch contact in a compact sequencer package.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTwo main switches plus one auxiliary switch for multi-stage electric heat control\u003c\/li\u003e\n\u003cli\u003eStaged element activation reduces inrush current and protects circuit breakers\u003c\/li\u003e\n\u003cli\u003eSold individually, suitable for replacement or new installation applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Copeland 24a55-1 electric heat sequencer provides reliable staged switching for electric furnace and air handler heating systems, featuring two main contacts and one auxiliary contact to manage multi-stage heat loads safely and efficiently.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: COPELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 24a55-1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Electric Heat Sequencer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Configuration\u003c\/strong\u003e: 2 Main Switches, 1 Auxiliary Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Size\u003c\/strong\u003e: 1 Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COPELAND","offers":[{"title":"Default Title","offer_id":51121060806962,"sku":"24A55-1","price":80.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304886173.jpg?v=1777747294","url":"https:\/\/voomisupply.com\/products\/copeland-24a55-1-electric-heat-sequencer-2-main-1-aux-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
