Motor protection circuit breaker, Class 10, 100 kA
At 45 mm wide and 75 mm deep, it fits standard motor starter combinations alongside contactors in the same rail footprint. The M3 screw terminals for the main circuit accept 2× (0.5…1.5 mm²) or 2× (0.75…2.5 mm²) solid or stranded wire. Clearance requirements: 20 mm upwards, 20 mm downwards, 9 mm at the side, 0 mm forwards and backwards.
Key protection features
No ground fault detection. The rated operational voltage range is 20…690 V. Operating temperature range -20…+60 °C, storage -50…+80 °C. Maximum switching frequency in AC-3 duty is 15 operations per hour. For short-circuit protection coordination, at 400 V use a gL/gG 40 A backup fuse; at 500 V and 690 V, gL/gG 35 A.
