The description confirms the part as XT4N 250 TMF 225-2250 3P F F UL/CSA — fixed front terminals, fixed rear terminals, and UL/CSA certification. This is the breaker you spec into a panel when you need the full UL and CSA listing for North American installations.
The 250 A frame with a TMF 225-2250 A trip means the breaker is rated for continuous current up to 225 A in that frame size, with the magnetic trip adjustable across the 225-2250 A range. That adjustable magnetic pickup is what lets you coordinate with downstream devices — set it high enough to ride through motor inrush on a compressor or conveyor start, but low enough to clear a bolted fault before the upstream feeder trips. For the panel builder, that means no extra third-party evaluation needed on the shop floor.
Deployment Context
Rated for distribution and motor branch circuits in industrial control panels, switchboards, and motor control centers. The TMF trip curve suits mixed loads with both resistive and moderate inductive components.
