- Description
Rated 40 A with 10 kA breaking capacity at 400 V AC, the ABB SH204M-C40 (SKU 2CDS274011R0404) is the four-pole, higher-current member of the SH200M miniature circuit breaker series. Its type C tripping characteristic trips instantaneously between 5 and 10 times In, which tolerates the inrush of small motors or transformers on three-phase-plus-neutral circuits, and it mounts on standard DIN rail in a 4-module, 70 mm wide housing.

Selection Notes
At In 40 A and 4P, the SH204M-C40 protects three-phase-plus-neutral circuits carrying more current than the lower-current, 2-pole members of the SH200M series, while keeping the same type C instantaneous-trip band (5-10× In) that tolerates motor and transformer inrush. Its 10 kA breaking capacity at 400 V AC covers typical distribution fault levels for this current rating without needing a current-limiting device upstream. Choose the 4-pole format specifically when the neutral conductor must be switched along with the three phases, not just protected.
