That means it handles high inrush currents without nuisance tripping, making it the right call for motor circuits, transformers, and capacitive loads where the start-up surge can hit 10–14× the rated current.
Combined terminals top and bottom simplify daisy-chaining busbars in a distribution board.
Environmental and compliance profile
Halogen-free and silicon-free construction suits clean-room or sensitive electronic environments. The 10 000 mechanical switching cycles are typical for this class — adequate for a protection device that operates rarely, not a daily-switched contactor.
