Its breaking capacity hits 52.5 kA at 240 V, 32 kA at 415 V, and holds 7.5 kA up to 690 V — enough to clear a high-fault weld-line feeder without cascading upstream. Current rating is 16 A flat from 40 °C to 55 °C, then derates to 15 A at 70 °C. That means it holds takt time in a warm panel without nuisance tripping. Insulation voltage rated at 800 V, so it handles 480/600 V systems with margin.
Standard 3-pole MCCB footprint — drops into a SENTRON panel or DIN-rail adapter without re-drilling. Spring-cage terminals accept 0.2–2.5 mm² solid or ferruled stranded; strip length 8 mm avoids whiskers.
