The TM240 thermal-magnetic trip unit handles overload and short-circuit response without external logic. Breaking capacity is 187 kA at 240 V, 121 kA at 415/440 V, and 52.5 kA at 690 V — figures that tell you whether this breaker clears a fault before the upstream gear takes damage.
Dimensions are 320 mm high, 210 mm wide, 120 mm deep. That depth is the critical number for gland-plate clearance and door swing — at 120 mm it fits most standard MCC buckets without a sub-panel spacer. Width of 210 mm means it occupies three pole spaces in a typical SENTRON mounting base.
If your spec calls for those, you are looking at a different 3VA variant.
