It's rated for 230 V AC at 50/60 Hz and carries a 50 kA breaking capacity under IEC 60947-2 — that's the rating that governs fault clearing in industrial panels where high prospective short-circuit currents are expected. The 76 mm depth includes the quick-assembly system and combined top/bottom terminals.
The 50 kA at 230 V AC (IEC 60947-2) is the headline number for selectivity studies. For DC circuits, it's rated 15 kA per IEC 60947-2. Under UL 1077 and CSA C22.2 No. 235, the breaking capacity is 5 kA — that's the figure a panel builder needs when the spec calls for UL-listed branch protection rather than IEC. Temperature derating is built in: at 45 °C the rated current is 3 A, dropping to 2.91 A at 50 °C and 2.81 A at 55 °C.
Installation notes
Mounts in any position on DIN rail. The neutral conductor is switched (1P+N), so it's not a straight 2-pole breaker — the neutral pole opens with the line pole, which matters for isolation requirements. The combined terminal at top and bottom accepts the same wire size range; the sealable option (yes) allows locking the cover after commissioning to prevent tampering. Halogen-free and silicon-free construction, so it's safe for use in clean-room or food-processing zones where outgassing is a concern.
