Product details

The 3-pole fixed configuration with front terminals (F F) is built for UL/CSA markets, meaning the trip curve and interrupting ratings are certified to North American standards alongside IEC. The thermal-magnetic trip gives you an inverse-time thermal element for overloads and a magnetic instantaneous element for short-circuits — no electronics to fail or need configuring, which is the right choice for a fixed-load MCCB that just needs to protect a feeder or a large motor branch circuit without adjustable trip settings.

The TMF 250-2500 trip unit adjusts from 250 A to 2500 A continuous current via the dial.

Panel integration

The XT4S frame mounts on DIN rail or backplate. Fixed front terminals accept standard busbar or cable lugs.
