The 2CCS471001R0134 is a 1-pole miniature circuit breaker with a C-curve trip characteristic, rated 13 A at 440 V insulation voltage. The 10 kA Icn (service breaking capacity) and 25 kA Icu (ultimate breaking capacity) give selectivity headroom for a 400 V distribution board; the Icu figure tells you the breaker can safely interrupt a fault up to 25 kA once and still be functional afterward, while Icn is the guaranteed performance for repeated operation.
Integration into the enclosure
The 69 mm width (roughly 4 module spaces) and 94.5 mm depth fit a standard distribution board or sub-panel. Screw terminals accept solid or stranded copper; strip length per ABB termination practice (typically 10–12 mm) avoids creepage issues at 440 V.
