The C-curve means it holds up to 5–10× rated current for short overloads before tripping — typical for motor-starting or transformer inrush where you need to ride through a brief surge without nuisance trips. The 6 kA Icn (rated short-circuit breaking capacity per IEC 60898) covers most residential and light commercial panel faults; the 20 kA Icu (ultimate breaking capacity per IEC 60947-2) tells you it can interrupt a higher fault once without damage, which matters for industrial sub-distribution where fault levels are higher. The bi-directional cylinder-lift terminals accept up to 2.8 Nm tightening torque — solid for copper conductors up to 25 mm².","metaTitle":"ABB 2CDS251103R0204 MCB, C-Curve 20A, 2-Pole, 6kA Icn","metaDescription":"ABB miniature circuit breaker, C tripping characteristic, 20 A rated current, 2 poles, 440 V insulation voltage, 6 kA Icn, IP20/IP40, DIN rail mount.

The difference is typically in the breaking capacity variant (6 kA vs 10 kA Icn) or the terminal design. If your fault level exceeds 6 kA, step up to the S200P or S200M series."},{"question":"What compliance documentation is available?","answer":"The part carries IEC 60898 and IEC 60947-2 ratings (Icn and Icu).
