The Icu rating of 20 kA is the ultimate breaking capacity per IEC 60947-2, a one-shot fault clearance figure that gives headroom for high-fault locations near transformers. For a 6 A B-curve MCB, the 20 kA Icu means it can be applied downstream of a larger upstream device without cascading failure, provided the prospective short-circuit current at its installation point does not exceed that value. ## Panel Integration and Enclosure Fit The 2-pole width is 35 mm (one module per pole), height 88 mm, depth 69 mm. The IP20 enclosure rating means finger-safe terminals when installed in a panel; IP40 applies to the front face, protecting against tools and small wires entering the actuator slot. The bi-directional cylinder-lift terminal accepts up to 2.8 Nm tightening torque, compatible with standard screwdrivers and ferruled conductors.","metaTitle":"ABB 2CDS251103R0065 S200 MCB, B Curve 6A 2-Pole, 6 kA Icn","metaDescription":"ABB S200 miniature circuit breaker, 6 A, B tripping characteristic, 2-pole, 440 V rated insulation voltage, 6 kA Icn / 20 kA Icu.
