The XT3NU3225AFJ000XXX: Mounts on a standard DIN rail or directly onto a backplate via the molded case footprint. The fixed front terminals accept lug or busbar connections typical for panelboard and switchboard builds. Rated 225 A continuous at 40 °C, so it suits feeder or large branch-circuit protection in commercial and industrial panels. The TMF trip unit provides thermal overload (inverse-time) and magnetic short-circuit (fixed instantaneous) protection — no field-adjustable trip settings.
