The XT1HU3100AFD000XXX: The TMF 100-1000 A trip unit covers a wide adjustment range, so one breaker can serve multiple motor or feeder circuits within that band — useful for stocking flexibility. The 125 A frame means the physical size and bus connection pattern stay constant even when the trip setting changes, simplifying panel layout and busbar drilling. Front terminals make it straightforward to land incoming and outgoing conductors without special adapters.
