Its Trip Class 10 means it trips within 10 seconds at 7.2× the thermal setting current — fast enough to protect standard induction motors during locked-rotor starts without nuisance tripping on normal acceleration. The 100 kA breaking capacity at 400 V AC (and across the 240–690 V AC range) means it safely interrupts fault currents up to that level without cascading upstream, so it can be used directly at the panel main bus in high-fault installations. The 45 mm width and 97 mm depth fit standard enclosure cutouts for size S00 devices — no special backplate or gland plate rework needed for a drop-in replacement in an existing panel.
Panel integration
The 45 mm width and 97 mm depth mean it occupies a single 45 mm DIN-rail slot — standard for size S00 breakers. Screw-type terminals on the main current circuit accept 2× (0.75–2.5 mm²) solid or stranded, or 2× 4 mm². The screwdriver shaft diameter is 5–6 mm, Pozidriv size 2. Clearance: 50 mm upwards and downwards, 30 mm at the side; no clearance needed forwards or backwards. Ambient operating range is –20 to +60 °C; storage and transport range is –50 to +80 °C.
