Product details

What this MCB delivers on the line

Breaking capacity — the number that matters for fault clearing

At the more common 220–240 V AC, that drops to 30 kA Icu; at 380–415 V AC, 15 kA Icu. For a 400 V distribution board, the Icn (service breaking capacity per EN/IEC 60898-1) is 10 kA — that is the rating for repeated clearing under normal service conditions. The C-curve means magnetic trip occurs at 5–10× In (40 A), so instantaneous trip is between 200 A and 400 A. That keeps the line moving: nuisance trips are rare on motor inrush or transformer energisation.

Snaps onto standard DIN rail. Width is 72 mm (8 × 9 mm pitches), depth 78.5 mm, height 91 mm.

Frequently asked questions
