It's the kind of breaker you'd spec into a distribution panel or motor branch circuit where you need a compact, high-interrupting device that doesn't take up a lot of DIN rail space. The TMF trip gives you a fixed thermal curve for overload protection and a magnetic trip for short-circuit events — no field-adjustable dials, which means less to go wrong and fewer callbacks.

What does the description XT3N 225 TMF mean?
XT3N is the frame size and series designation. 225 A is the continuous current rating of the TMF (thermal-magnetic fixed) trip unit. The TMF trip provides a fixed thermal overload curve and a magnetic short-circuit trip — no field adjustment, but reliable and repeatable.
