Product details

What this MCB does and where it fits

It breaks up to 25 kA at 400 V AC per IEC 60947-2, and 5 kA per UL 1077 and CSA C22.2 No. 235 — so it handles both IEC and North American panel specs.

Accepts solid or stranded conductors from 0.75 to 35 mm² at the screw terminals, torqued to 2.5–3.5 N·m. Combined top and bottom terminals let you daisy-chain busbars without extra lugs.
