The 100 kA breaking capacity at 240 V, 400 V, 500 V, and 690 V AC means this breaker handles high prospective fault currents common in industrial distribution — it's rated for installation at the motor branch, not just downstream of a current-limiting fuse. The Trip Class 10 means the thermal trip element will open within 10 seconds at 7.2× the thermal setting current, matching standard IEC 60947-4-1 requirements for motor starting duty. No ground fault detection, so that function must come from a separate device or upstream GFCI.
The screw and snap-on mechanism onto 35 mm DIN rail means it clips on without tools and can be screw-fastened for vibration resistance. Clearance requirements: 50 mm upward and downward, 30 mm to the side, 0 mm forward and backward (–,) — so it can be stacked tight front-to-back but needs breathing space above and below for thermal dissipation. Terminal capacity on the main contacts accepts 2× (1 to 2.5 mm²) or 2× (2.5 to 10 mm²) solid or stranded, with M4 screw terminals.
