The TM240 thermal-magnetic trip unit provides adjustable overload protection (Ir = 440…630 A) and fixed short-circuit pickup (Ii = 4…8 × In), so it fits a feeder or large motor branch where the full-load current sits inside that band.
Shunt trip and accessory integration
That means remote tripping from a safety PLC or E-stop circuit is wired directly — no field retrofit, no extra enclosure space for an add-on module. The shunt occupies the left accessory slot; the right slot remains free for an auxiliary switch or alarm contact if the panel design calls for status feedback.
