The ABB XT5HU430ABFF000XXX is a molded case circuit breaker (MCCB) in the XT5H 400 TMA frame, carrying the description GED XT5HU430ABFF000XXX XT5H 400 TMA/ABB 1SDA102635R1 XT5H 400 TMA. The TMA designation indicates a thermal-magnetic trip unit — thermal for overload protection, magnetic for short-circuit — sized for the 400 A frame. This is the part you'd pull for a panel build or line-down swap where the nameplate calls out that specific ABB order code.
The XT5H 400 TMA frame is a common footprint in ABB's molded case breaker lineup, used across industrial distribution panels, motor control centers, and feeder circuits. The thermal-magnetic trip gives fixed overload and short-circuit protection without the need for external trip units or auxiliary power. Mounts in standard panelboard or switchboard cutouts; the rotary handle and accessory slots are consistent with the XT5 family.
