Its TM240 thermal-magnetic release handles overload and short-circuit trip curves without undervoltage or shunt-trip add-ons — that's another SKU I don't need on the shelf. Interrupting capacity hits 121 kA at 240 V AC and still delivers 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V — enough headroom for most industrial service-entrance or feeder panels without cascading upstream breakers. Power dissipation maxes at 12 W — negligible in a ventilated enclosure but worth noting for sealed, high-density layouts.
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration. The 70 mm depth keeps it clear of shallow backpanels and leaves room for rear bus connections. Trip indicator is present, so a quick visual scan tells you which breaker opened.
The base switch part number is 3VA11204EF320AA0 — useful for cross-referencing internal BOMs or ordering the switching mechanism separately if the trip unit is field-replaceable.
