Engineered for compatibility with the 2025\/2026 generation of R-454B HVAC systems, this heater kit is essential for maintaining indoor comfort in larger homes during extreme cold snaps when heat pump efficiency may decline. With its specialized slide-in design, this unit integrates directly into the blower compartment of J5AH4 and J5AH5 air handlers, offering a robust and safe secondary heat source that can satisfy the heating demands of a 4 to 5-ton system.\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e20kW heating capacity providing approximately 68,242 BTU\/h of supplemental heat\u003c\/li\u003e\n    \u003cli\u003eDual integrated 60-amp circuit breakers for maximum safety and electrical compliance\u003c\/li\u003e\n    \u003cli\u003eOptimized for use with R-454B compliant J5 series air handlers\u003c\/li\u003e\n    \u003cli\u003eQuick-connect wiring harness facilitates a faster and more secure field installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\n\u003cp\u003eSafety and durability are prioritized in the 5JAYHTR1A20BKA design. It features high-grade nickel-chromium heating elements and automatic-reset thermal limit switches to ensure the unit does not overheat during extended run times. Because of its high power requirements, this 20kW model includes two built-in circuit breakers that function as local disconnects, simplifying the high-voltage wiring process and meeting most local building codes. Constructed with heavy-duty galvanized steel, this heater kit is built to handle the high-static airflow of large air handlers, providing years of reliable, maintenance-free backup warmth.\u003c\/p\u003e\n\n\u003ch3\u003eProduct Information\u003c\/h3\u003e\n\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Oxbox (A Trane Brand)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMPN\u003c\/strong\u003e: 5JAYHTR1A20BKA\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5JAYHTR Electric Heat\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Electric Heater Kit\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHeating Capacity (kW):\u003c\/strong\u003e 20.0 kW\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHeating Capacity (BTU\/h):\u003c\/strong\u003e 68,242 @ 240V \/ 51,182 @ 208V\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 208\/240V\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePhase:\u003c\/strong\u003e 1\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHertz:\u003c\/strong\u003e 60\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCircuit Breakers:\u003c\/strong\u003e Included (2 x 60 Amp)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMinimum Airflow Required:\u003c\/strong\u003e ~1400 - 1600 CFM (Refer to unit manual)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRefrigerant Compatibility:\u003c\/strong\u003e R-454B \/ R-410A Systems\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Galvanized Steel \/ Nickel-Chromium Elements\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNet Weight:\u003c\/strong\u003e 14.5 lbs\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 15.0\" L x 8.5\" W x 5.75\" H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OXBOX","offers":[{"title":"Default Title","offer_id":51031849533746,"sku":"5JAYHTR1A20BKA","price":364.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5JAYHTR1A20BKA.1774965767385.webp?v=1775055684","url":"https:\/\/voomisupply.com\/products\/oxbox-5jayhtr1a20bka-20kw-electric-heater-kit-with-built-in-circuit-breakers-r-454b-compatible","provider":"Voomi Supply","version":"1.0","type":"link"}
