Product details

The XT4NU3070AFJ000XXX: The "250" frame size means this MCCB handles continuous current up to 250 A in a compact footprint. The TMF 70-700 trip unit gives an adjustable thermal (overload) range from 70 to 700 A and a fixed magnetic (short-circuit) pickup — so you dial the overload protection to match your load cable, but the instantaneous trip is set at the factory. That 3-pole configuration covers three-phase circuits; the F F designation means line and load terminals are both front-connected, which keeps the panel layout clean and the busbar runs short.

The UL/CSA listing means it's accepted across North American industrial installations without extra agency review.
