Its Class 10 trip characteristic means it will trip within 10 seconds at 7.2× the thermal setting — fast enough to protect standard induction motors during locked-rotor conditions without nuisance tripping on normal starts. The 100 kA breaking capacity at 400 V and 690 V AC tells you this breaker can safely interrupt fault currents up to that level without upstream fuses or cascading failure — a key spec for SCCR compliance in industrial panels. Screw-type terminals for the main current circuit accept 2× (0.5…1.5 mm²) or 2× (0.75…2.5 mm²) solid or stranded.
Integration — clearances and environment
Clearance requirements: 50 mm upwards, 50 mm downwards, 30 mm at the sides, zero forwards and backwards. Operating temperature range is -20 to +60 °C, storage and transport -50 to +80 °C. Temperature compensation is active across the full operating range.
