Rated breaking capacity is 6 kA per IEC/EN 60898-1 and 30 kA per IEC 60947-2, so it handles fault currents up to 30 kA at 400 V AC in an industrial installation. The 18 mm width (1 modular unit) snaps onto DIN rail and fits standard enclosure cutouts.
Breaking capacity — what the ratings mean
This MCB is rated for three different fault-current standards. Under EN 60898-1 (household-type coordination) it interrupts 6 kA. Under IEC 60947-2 (industrial coordination) it handles 30 kA at 400 V AC, and 15 kA at 60 V DC. For UL 1077 recognition it carries 5 kA.
Mounting and integration details
Depth is 76 mm (70 mm installation depth behind the panel), width 18 mm (1 modular unit), height 90 mm. Sealable terminals allow lockout/tagout. Halogen-free and silicon-free construction, so it won't outgas corrosive compounds in sealed enclosures.
Complies with IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 / CSA C22.2 No. 235.
