ABB XT1HU3030AFF000XXX Molded Case Circuit Breaker

ABB XT1HU3030AFF000XXX Molded Case Circuit Breaker (MCCB) from the Tmax XT family. This 3-pole device is built on the XT1 frame (125 A) and is rated for 30 A with a thermal-magnetic trip (TMF) for overload and short-circuit protection. It is intended for low-voltage distribution panels and motor feeders, offering protection up to 600 V across three-phase systems (600Y/347/690 VAC configurations) with a 50/60 Hz operating frequency and a 25 kA interrupting rating. The breaker features front-line/load-side connection and a double-insulated construction, designed for panel mounting in industrial environments. Its dimensions are 5.12 in high, 3.0 in wide, and 2.75 in deep, and the unit is UL/CSA listed for North American use. Operating temperature range is -13 to 158 F (-25 to 70 C), ensuring reliable performance in typical plant environments. This XT1HU model is part of ABB’s robust Tmax XT line, delivering precise thermal-magnetic protection for circuits requiring a 30 amp, 3-pole MCCB with compact enclosure and front-access terminals.
