| Design Of The Product | for motor protection |
Rated breaking capacity reaches 50 kA at 400 V AC, with 100 kA at 240 V, 8 kA at 500 V, and 5 kA at 690 V — so it handles high fault currents in industrial distribution without upstream cascading.
Dimensions: 70 mm wide, 165 mm high, 174 mm deep. Main circuit terminals accept solid conductors 2x (2.5–16 mm²) or stranded 2x (10–50 mm²) and 1x (10–70 mm²); auxiliary and control circuits use separate screw terminals. AWG equivalents: 2x (10–1) for solid, 2x (10–2) for stranded.
Solid 2x (2.5–16 mm²) or stranded 2x (10–50 mm²) and 1x (10–70 mm²).
