The Airpax HH83XB428 is a genuine OEM circuit breaker designed for Carrier HVAC equipment, configured as a three‑pole device rated at 12 A and 600 V. As a drop‑in replacement, it protects Carrier electrical circuits by interrupting overloads in 600 V systems and is documented in HVAC catalogs as Carrier HH83XB428, underscoring its role as an authentic service part. Verified compatibility listings show it fits Carrier models such as 5CP2 07014, 48TJD024 670, and 50P3 10010, making it a common OEM substitute when servicing Carrier air handlers and condensers. In HVAC parts catalogs, the HH83XB428 (also seen as HH83XB428‑B in some listings) is presented as an official Carrier replacement part, so confirming exact fit with your unit’s service documentation is essential before ordering.
