The Oxbox 5JAYHTR1A Series electric heat kit adds supplemental electric heat to Oxbox R-454B air handlers in the J5AH4 and J5AH5 multi-positional series. Three capacities are available — 8 kW, 10 kW, and 15 kW — with an integrated circuit breaker factory-installed on every kit.
The kit mounts inside the air-handler cabinet and provides backup electric heat for heat-pump systems or primary electric heat when installed without a furnace. Sizing is driven by tonnage and regional heating load; consult the air-handler install manual for per-model kW compatibility.
Fits: Oxbox J5AH4 and J5AH5 multi-positional R-454B air handlers (1.5 – 5 ton).
Capacities: 8 kW, 10 kW, 15 kW. Each kit includes an integrated circuit breaker.
