That certifies its short-circuit making and breaking capacity, its isolation suitability (marked 'Yes' per IEC 60947-2), and its utilisation category A — meaning it is not intended for frequent switching of motor loads, but for distribution-circuit protection where the breaker sees occasional switching, not daily cycling. The TM-D trip unit is thermal-magnetic: the thermal bimetal handles overload protection (long-time delay), the magnetic coil handles short-circuit instantaneously. No earth-leakage protection built in — that would need an add-on module.
Where it sits in the panel
Mounts on a backplate — no DIN rail required, though the 9-module pitch (9 mm per pole, so 27 mm total width) matches standard DIN-rail spacing if you use a DIN adapter. Width is 81 mm, height 137 mm, depth 80 mm. Connection terminals are front-facing, both upside and downside, which simplifies busbar routing in a distribution board. The Everlink lug terminals accept 2.5 to 70 mm² flexible copper or 2.5 to 95 mm² rigid/stranded copper — sized for the 160 A feed. Connection pitch is 35 mm with spreaders, 27 mm without; that matters when you are laying out busbar take-off points.
Listed as current production — no NRND or obsolescence flag on this code. That means it is still a standard catalogue item, not a last-time-buy orphan. No official successor exists because none is needed — this is the current build.
