Product details

Its tripping characteristic A makes it fast-acting — suited for protecting semiconductor loads or long cable runs where short-circuit current rises quickly, not motor feeders where inrush would nuisance-trip a B-curve. Breaking capacity is 10 kA per EN 60898-1 and 20 kA per IEC 60947-2 at 400 V AC, with 15 kA at DC per IEC 60947-2 and 5 kA per UL 1077 / CSA C22.2 No.235. That dual-rating means the same unit qualifies for both residential-distribution (EN 60898) and industrial-panel (IEC 60947-2) duty — the 20 kA figure is the one an integrator uses for SCCR calculations in a 480Y/277 V panel.

Snap-on quick-assembly system mounts in any position. Rated for -40 °C to 75 °C ambient, so it survives unheated enclosures in northern plants. Pollution degree 3, overvoltage category III, and vibration resistance per IEC 60068-2-6 (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz) — it holds up in panels mounted on vibrating machinery or near conveyors.
