It is rated 63 A at 40 °C with a breaking capacity of 16 kA at 415 V AC (performance level E), certified to EN/IEC 60947-2. The TM-D trip unit combines a thermal bimetal for overload protection and a magnetic coil for short-circuit protection — no earth-leakage module built in.
Above that, the thermal curve derates — if your panel runs hotter, you may need a higher frame. The 3P (three-pole) version switches all phases together, required for three-phase distribution or motor branch circuits.
Mounts on a backplate (not DIN rail — the ComPacT NSXm uses a screw-fixed backplate mount). Accepts horizontal or vertical orientation, flat on the back. The Everlink lug terminals on both line and load sides accept 2.5–95 mm² rigid aluminium/copper or 2.5–70 mm² flexible copper — that's a wide range covering most panel feeders. Connection pitch is 35 mm with spreaders, 27 mm without. The toggle handle gives local manual switching, and the green flag signals auxiliary contact presence. IK07 impact rating handles accidental tool drops.
