Rated breaking capacity sits at 30 kA at 400 V, dropping to 4 kA at 500 V and 2 kA at 690 V — the 400 V figure is the one that governs most 400 V line-side fault scenarios in industrial panels. Motor power assignments are 18.5 kW at 230 V, 50 hp at 460/480 V, and 62 A at 600 V, so it covers a 50 hp motor on a 480 V North American supply or an 18.5 kW European-rated motor at 230 V.
Trip class and protection logic
Ground fault detection is not included — if that's required, you'd add a separate ground-fault relay or choose a variant with that feature.
Dimensions are 55 mm wide, 140 mm tall, 149 mm deep — the 55 mm width is a standard 3-module footprint on a DIN rail, so it occupies three 18 mm slots. Main circuit terminals accept 2×(1–35 mm²) or 1×(1–50 mm²) solid or stranded copper, with M6 screw terminals.
