Not for motor starting or heavy inductive loads; those call for C or D curves. Sealable, so it can be locked in the OFF position for lockout/tagout without padlocking the whole panel.
That dual rating means it qualifies for residential panels and light commercial distribution boards alike — no need to overspec for industrial coordination studies. Storage range wider, but that's handling, not running. Mechanical service life: 10 000 operating cycles typical. For a fixed installation that's rarely cycled, effectively lifetime; for a test bench or frequent-switching application, consider a contactor instead.
Panel integration
Installation depth 70 mm behind the panel surface; overall depth 76 mm including the front. Three 18 mm width units = 54 mm total busbar space. Accepts busbar comb for daisy-chaining downstream breakers. Rated for overvoltage category III and pollution degree 2 — standard for fixed-installation distribution boards. 50/60 Hz supply frequency, so it works on both 50 Hz and 60 Hz systems without derating.
