Breaking capacity is 50 kA at 400 V AC, 100 kA at 240 V AC, 12 kA at 500 V AC, and 5 kA at 690 V AC — covering most industrial supply points without needing an upstream current-limiting fuse for high-fault panels. Built-in phase failure detection trips the breaker if one phase drops out, preventing single-phasing damage on three-phase motors. No ground fault detection — that's handled separately if needed.
Dimensions are 55 mm wide, 140 mm high, 149 mm deep — fits a standard 3-pole MCCB slot. No side clearance needed (0 mm backwards, 0 mm at the side) so you can pack breakers tight on the rail. Main terminals accept 2x solid conductors up to 16 mm² or 2x stranded up to 25 mm² (1x up to 35 mm²). AWG equivalents: 2x 18–2 AWG solid, 1x 18–2 AWG. Finely stranded with ferrules: 2x 0.75–16 mm² or 0.75–25 mm² single.
Shock rated 25g for 11 ms. IP20 protection on the front (finger-safe, not washdown). RoHS compliance date: July 1, 2006. Mounting position any — no derating for side or upside-down installation. Power dissipation: 14.5 W total in hot operating state, 4.8 W per pole. At 15 operations per hour maximum (AC-3 duty), thermal management in a sealed enclosure is straightforward.
