Product Description

The Oxbox 5JAYHTR1A08BK is an 8 kilowatt electric auxiliary heat kit designed for installation inside compatible residential air handler systems. It delivers supplemental and emergency electric heat when outdoor temperatures drop below the efficient operating range of a heat pump. Built to integrate directly into the air handler cabinet, this kit is rated for 208/230V single-phase 60 Hz power and draws a minimum circuit amperage of 7.5 amps with a maximum circuit breaker rating of 40 amps. Licensed HVAC technicians install this component as part of a heat pump or air handler system upgrade or replacement. Oxbox is a Trane brand, and this kit is engineered to meet R-454B refrigerant system compatibility standards.

The 5JAYHTR1A08BK is suited for residential heat pump and air handler installations where supplemental electric heat is required. It functions as an auxiliary heat source during low-ambient conditions and as an emergency heat backup if the heat pump compressor is taken offline. Submittal sheet data from Oxbox system documentation lists this kit in configurations compatible with select Oxbox J5AH-series and related air handler models. Refer to the specific air handler submittal sheet to confirm fitment before ordering.
