The 250 A frame and TMF 150-1500 A trip range cover a wide motor and feeder band. The fixed thermal-magnetic design means the overload curve is set at the factory — no field-adjustable thermal dial, so you size it to the load's full-load amps and lock it in. UL/CSA listing tells the inspection authority it's accepted for branch-circuit protection in North American panels without a separate fuse or supplementary protector.
