Breaking capacity of 10 kA Icu at 440 V AC per EN/IEC 60947-2 means it can safely interrupt a fault current up to 10,000 A at that voltage without welding its contacts or cascading failure upstream. At 400–415 V the rating rises to 15 kA Icu, and at 230–240 V it reaches 30 kA Icu — giving solid selectivity headroom in a residential or light commercial distribution board. Two protected poles in a 2P form factor, thermal-magnetic trip unit. The Multi9 C60H series is a DIN-rail mounted design for panel integration — standard 18 mm per pole width, clips onto the rail without tools.
Snap-on DIN-rail mount, 36 mm wide for the 2P unit. Rated for distribution duty (EN 60898 and EN/IEC 60947-2), so it's at home in a consumer unit, sub-distribution board, or control panel feeder circuit. The C-curve suits mixed loads — lighting, socket outlets, small motor circuits — where the start-up surge is above resistive but below heavy motor inrush.
