It's not a general-purpose distribution breaker; the design-of-product field confirms it's for starter combinations, so the trip curve and breaking capacity are tuned for motor-starting inrush rather than lighting or resistive loads. At 240 V it's rated 100 kA, which covers most North American industrial services. Motor power assignment: 18.5 kW at 230 V, 25 hp at 220/230 V, 50 hp at 460/480 V, 60 hp at 575/600 V. That lines up with a NEMA size 3 or 4 contactor range — useful for medium-horsepower pumps, compressors, and conveyors on a 480 V plant bus.
Panel fit and clearances
Width is 55 mm — that's three standard 18 mm module widths, so it occupies three slots on the rail. Depth is 149 mm, height 140 mm. Plan for 50 mm clearance above and below, 10 mm to the sides, and zero forward or backward clearance required. That zero forward clearance means it can sit flush against a gland plate or back panel without derating. Terminals accept 2x 1–35 mm² or 1x 1–50 mm² solid or stranded copper. Main contact terminals are M6 screw-type.
