It carries a CLASS 10 trip characteristic, meaning it will trip within 10 seconds at 7.2× the thermal setting — fast enough to protect standard induction motors during a locked-rotor event. The 100 kA breaking capacity at 400 V and 480 V means it can safely interrupt a bolted fault up to that level without the upstream breaker needing to clear it, which simplifies coordination in a distribution panel.
The 45 mm width takes up one 45 mm slot; depth is 97 mm, so it clears a 100 mm deep enclosure with a few mm to spare for wiring. Screw-type terminals on the main circuit accept 2× (0.5…1.5 mm²) or 2× (0.75…2.5 mm²) solid or stranded. Mounting position is any, which helps when you're cramming breakers into a tight sub-panel and need to rotate them for wire routing.
The 100 kA SCCR at 400 V and 500 V is the key number for a panel builder: it means this breaker can be used on a supply with up to 100 kA available fault current without needing a current-limiting fuse upstream. At 690 V the breaking capacity drops to 4 kA — still adequate for most 690 V motor circuits, but check your available fault current if you're feeding from a large transformer. The rated operational voltage range is 20…690 V, covering 208 V through 600 V common in North American and European installations.
