The 6 kA Icn (service breaking capacity per EN 61009) and 10 kA Icu (ultimate capacity per IEC 60947-2) tell you it can safely interrupt a fault up to 10 kA without damage, which covers the majority of domestic and light commercial panel fault levels. ## Where it fits — panel integration and environment The IP20 enclosure protects against finger contact; Rated insulation voltage 500 V gives headroom for 400 V three-phase networks.","metaTitle":"ABB 2CSR255180R1044 RCBO, 4 A, 2-Pole, C-Curve, 6 kA","metaDescription":"ABB 2CSR255180R1044 RCBO, 4 A rated, 2-pole, C-trip curve, 6 kA Icn / 10 kA Icu, IP20/IP40, DIN rail mount.
