It combines a CLASS 10 trip curve with phase failure detection, meaning it will disconnect a motor within 10 seconds at 7.2× rated current and also trip if one phase drops out — a common failure mode that cooks windings. Rated operating voltage spans 20 to 690 V, and the unit delivers 100 kA breaking capacity at 400 V, which is enough to handle high-fault-current industrial panels without cascading upstream.
The 45 mm width is a standard 2.5 module footprint — fits alongside contactors in a typical motor starter combo. Any mounting position is allowed. Main circuit terminals are M3 screw-type, accepting 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²). Keep the strip length clean; the M3 screws need a proper torque to avoid hot spots at full load.
