It protects branch circuits against overload and short-circuit in final distribution panels, rated 400 V AC at 50/60 Hz. Breaking capacity hits 15 kA per IEC 60898 and 50 kA per IEC 60947-2 — the higher figure covers industrial panel duty where fault current can run hot. For UL 1077 / CSA C22.2 No. 235 installations, it's rated 5 kA. The IP20 enclosure (with conductors connected) suits enclosed distribution boards — not washdown environments.
Depth of 76 mm and installation depth of 70 mm mean it clears standard 80 mm deep enclosures. Ambient range -40 °C to 75 °C, with humidity derating above 55 °C (95% RH up to 55 °C, then 55% to 70 °C, 35% to 75 °C).
