ABB XT1HU3080AFF000XXX Molded Case Circuit Breaker

The ABB XT1HU3080AFF000XXX is a 3‑pole molded‑case circuit breaker (MCCB) in the Tmax XT1H family, designed for UL/CSA‑listed installations and 600V class distribution. It carries an 80 A rated current, uses a thermal‑magnetic (TMF) trip unit, and offers a 25 kA short‑circuit interrupting capability at 600Y/347V. This HU variant represents the 25 kAIC option within the XT1 80 A frame; ABB also lists XT1NU3080AFF000XXX (18 kAIC) and XT1SU3080AFF000XXX (22 kAIC) variants for the same frame. The XT1HU3080AFF000XXX is a 3‑pole device compatible with 600V AC systems (600Y/347V line‑to‑line/line‑to‑neutral) and UL/CSA standards. This combination of current rating, high short‑circuit rating, and TMF tripping makes it suitable for protecting three‑phase feeders and motors in industrial power distribution.
