Its CLASS 10 trip class means the bimetal overload release will trip within 10 seconds at 7.2× the set current — the standard for standard-duty motor starting where the acceleration time stays under 10 seconds. The adjustable overload release spans 5.5 to 8 A, and the fixed magnetic short-circuit trip responds at 104 A.
The S00 footprint (45 mm wide) shares the same rail spacing as the SIRIUS contactor range, so the breaker and contactor can be ganged side-by-side without extra bus bars.
Rated operational current is 8 A at 400 V AC, corresponding to a motor rating of 3 000 W at 400 V. Power dissipation in hot operating state is 9.25 W total (3.1 W per pole). The breaker includes phase-failure detection and provides short-circuit protection without requiring separate fuses for most installations within its breaking capacity.
