It combines a CLASS 10 trip curve with phase failure detection, so it protects three-phase induction motors from overload and phase loss — the most common cause of motor winding failure on production lines. That gives you full selectivity headroom in a 400 V MCC. Spring-loaded terminals accept 2x (0.5 to 2.5 mm²) solid or stranded wire — no screw torque to verify, no loose connections from vibration on a conveyor line.
Clearance: 50 mm upwards and downwards, 30 mm at the side. That's the minimum free air space for arc quenching and heat dissipation — factor it into your gland plate layout.
