The 4-pole (4P) configuration handles three-phase plus neutral, common in European and IEC 60947-2 compliant panels. The TM-D trip unit is fixed thermal-magnetic, not electronic — so the thermal curve responds to overloads and the magnetic element clears short-circuits. There is no earth-leakage protection built in (: Without), so if you need residual current detection, you will add an external RCD or a separate Vigi module downstream. Mounts on a backplate, accepts front connections via compression lugs or busbars. The 108 mm width and 137 mm height fit standard enclosure cutouts. IP40 front-face protection means it is splash-proof from the front but not hose-down rated — suitable for indoor panels, not washdown zones.
Lifecycle stage is current — this is an active catalogue item, not a phase-out or NRND part. No last-time-buy window to watch for.
Connection pitch is 35 mm with spreaders, 27 mm without. The neutral is on the left. The toggle control is front-accessible; the local signalling flag (green) indicates presence of auxiliary contacts. Mechanical durability is 20 000 cycles; electrical durability is 20 000 cycles at 440 V at In/2, and 10 000 cycles at 440 V at In — so expect longer life under half-load switching than full-load.
