It provides supplemental or emergency electric heat by integrating directly into a compatible air handler cabinet. The kit includes a built-in circuit breaker, which simplifies the electrical installation by eliminating the need for a separate disconnect in many configurations. Licensed HVAC technicians install this kit as part of a split-system heat pump or straight-cool setup that requires electric strip heat capability. The assembly is designed to mount inside the air handler and connect to the existing blower and control wiring.\u003c\/p\u003e\n\u003cp\u003eThis heater kit is suited for residential air handler applications where electric resistance heat is required as primary supplemental heat or as emergency backup heat in a heat pump system. It is sized for 2-ton equipment and is a common field-installed accessory on qualifying RHEEM and Ruud air handler units. The integral circuit breaker provides overcurrent protection for the heating element, streamlining compliance with NEC requirements for electric heating equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10 kW electric resistance heating output for 2-ton air handler systems\u003c\/li\u003e\n  \u003cli\u003eIntegrated circuit breaker provides built-in overcurrent protection\u003c\/li\u003e\n  \u003cli\u003eField-installed accessory kit designed for air handler cabinet mounting\u003c\/li\u003e\n  \u003cli\u003eSuitable for supplemental or emergency heat in heat pump applications\u003c\/li\u003e\n  \u003cli\u003eEliminates need for a separate electrical disconnect in qualifying installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style electric heater kit accessory for qualifying 2-ton RHEEM and Ruud residential air handler units that accept the RXHJ series heater kit configuration.
