The XT1HU3045AFF000XXX: The XT1H frame is designed for DIN-rail or screw-mount installation inside distribution boards and motor control centers. The 125 A frame size keeps the footprint compact for a 3-pole breaker rated up to 500 A trip — the TMF element handles the overload and short-circuit protection, while the frame carries the interrupting rating. For a panel-builder, the front-connection terminals simplify wiring and busbar layout compared to rear-connected alternatives.
