Its Trip Class 10 means it will trip within 10 seconds at 7.2× the thermal setting current, which is the standard for standard-duty motor starting — it handles normal acceleration without nuisance tripping but clears a stalled rotor fast enough to protect the winding insulation. Rated for 100 kA short-circuit breaking capacity at 240 V, 400 V, and 500 V, this breaker can be installed on high-fault-current panels without needing upstream current-limiting fuses in most industrial distributions. At 690 V the SCCR drops to 4 kA, so on 690 V systems verify the available fault current stays below that. No ground fault detection on this variant.
The 45 mm width (three 15 mm modules) fits standard enclosure rail spacing. Any mounting position is allowed, which simplifies layout in crowded panels. Dimensions are 97 mm high × 45 mm wide × 97 mm deep. Clearance requirements: 50 mm above and below, 30 mm to the sides, 0 mm forward and backward — so it can be packed tightly front-to-back against a backplate or busbar.
