It delivers supplemental or primary electric heat by integrating directly into the air handler cabinet, adding resistance heating capacity to the airstream. The kit ships with a built-in 60-amp circuit breaker, eliminating the need for a separate disconnect in many installations. Rated for 208\/240-volt single-phase power at 60 Hz, this heater kit is also engineered for compatibility with R-454B refrigerant systems, making it a forward-compatible choice for newer equipment. Licensed HVAC technicians handling air handler add-on heat applications are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis heater kit is suited for residential air handler installations where supplemental electric heat is required. Typical applications include heat pump systems needing backup or emergency heat, or all-electric forced-air systems where a gas heat source is not available. The unit requires a minimum airflow of approximately 1000 CFM to operate safely — refer to the specific unit manual for exact airflow tables based on installed capacity. The kit is designed for multi-positional air handlers supporting upflow, downflow, and horizontal configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10kW electric resistance heating output for substantial supplemental heat capacity\u003c\/li\u003e\n  \u003cli\u003eBuilt-in 60-amp circuit breaker included — no separate disconnect required in qualifying installs\u003c\/li\u003e\n  \u003cli\u003e208\/240-volt single-phase, 60 Hz operation covers standard residential electrical services\u003c\/li\u003e\n  \u003cli\u003eR-454B refrigerant compatible, supporting next-generation low-GWP system pairings\u003c\/li\u003e\n  \u003cli\u003eMinimum airflow requirement of approximately 1000 CFM protects elements from overheating\u003c\/li\u003e\n  \u003cli\u003eDesigned for multi-positional air handler installations including upflow, downflow, and horizontal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style electric heater kit add-on for compatible Oxbox multi-positional air handlers.

Disconnect and lock out all power to the air handler before inserting or servicing the heater kit. Verify that the branch circuit ampacity and overcurrent protection at the panel meet the unit's minimum circuit ampacity requirements before energizing. Do not operate the heater kit below the minimum required airflow, as insufficient airflow can cause element overtemperature and premature failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeating Capacity\u003c\/strong\u003e: 10kW\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 208\/240 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCircuit Breaker\u003c\/strong\u003e: Included, 60 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Airflow Required\u003c\/strong\u003e: approximately 1000 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefrigerant Compatibility\u003c\/strong\u003e: R-454B\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: Oxbox\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5JAYHTR1J10BKA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OXBOX","offers":[{"title":"Default Title","offer_id":51031847993650,"sku":"5JAYHTR1J10BKA","price":346.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308797605.webp?v=1780589047","url":"https:\/\/voomisupply.com\/products\/oxbox-5jayhtr1j10bka-10kw-electric-heater-kit-with-built-in-circuit-breaker-r-454b-compatible","provider":"Voomi Supply","version":"1.0","type":"link"}
