It's rated for distribution duty per EN/IEC 60947-2, with a breaking capacity of 18 kA Icu at 380/415 V AC 50/60 Hz — that's the fault current it can safely interrupt at the most common industrial voltage without welding contacts or cascading upstream. The TM-D trip combines a thermal bimetal for overload protection (L) and a magnetic coil for short-circuit protection (I), both factory-set and sealed. At 220/240 V AC the breaker delivers 36 kA Icu, and at 440 V AC it holds 15 kA Icu — so the same unit covers a range of service voltages without a frame change, as long as the available fault current stays within the curve for the installed voltage.
Front connections top and bottom, 35 mm connection pitch. Mounts horizontally or vertically flat on the backplate — no derating for orientation per the datasheet. IP40 enclosure protection, IK07 impact resistance.
Current-production part per the manufacturer's lifecycle stage.
Mechanical durability is 20,000 cycles; electrical durability is 20,000 cycles at 277 V at half rated current, 10,000 cycles at full rated current. Suitability for isolation is confirmed per EN/IEC 60947-2, meaning the open contacts provide a visible-break isolation gap. Power dissipation per pole is 5.47 W — 10.94 W total for the 2-pole unit at full load. That's the heat the panel ventilation has to shed; factor it into the enclosure thermal budget.
