It snaps onto a 35 mm DIN rail per DIN EN 60715 and accepts screw-type terminals for the main current circuit, handling conductors up to 2x 35 mm² or 1x 50 mm² solid or stranded.
At 400 V the interrupting rating is 50 kA, which covers most industrial service-entrance and distribution panel fault levels. At 240 V it handles 100 kA, at 500 V it drops to 5 kA, and at 690 V it still manages 4 kA — enough for most motor branch circuits in a 480 V or 600 V plant. The continuous current rating at 480 V is 59 A, and the same at 600 V, so this breaker is sized for motor full-load currents in the 50–60 A range on a 480 V system.
Width is 55 mm, height 140 mm, depth 149 mm. Mounting position is any orientation. Minimum clearance to adjacent metalwork: 50 mm above and below, 10 mm at the sides — no additional clearance needed at 240 V, but at 400 V you need 160 mm above, 125 mm at 500 V, and 100 mm at 690 V for arc-flash containment.
Maximum switching frequency under AC-3 duty is 15 operations per hour, which suits motor starting cycles on pumps, fans, and conveyors — not high-speed jogging applications.
