Product details

What this MCB does on the line

The dual breaking capacity — 6 kA per EN 60898-1 and 15 kA per IEC 60947-2 — means it can be specified into a 400 V AC panel where the prospective fault current at the distribution board is up to 15 kA, a common requirement for industrial sub-distribution.

At 72 mm wide (4 modular width units) and 76 mm deep (70 mm installation depth), it fits a standard 4-pole MCB slot in a SENTRON distribution board or a third-party enclosure. The combined terminal at top and bottom accepts both busbar and cable, and the terminals are sealable for panel-lockout procedures.
