This ABB 2CDS271337R0407 is a 1-pole miniature circuit breaker from the System pro M compact S200 series, with a K-tripping characteristic and an 8 A rated current. Rated short-circuit breaking capacity Icn is 11.2 kA, with an ultimate Icu of 15 kA at 440 V — enough headroom for most commercial and light industrial panelboards where the prospective fault current stays under that ceiling. IP20 at the front (finger-safe terminals), IP40 for the enclosure body — fine for clean indoor panel environments; no washdown rating here.
Panel Fit
Width 17.5 mm per pole — standard 1-module footprint on DIN rail. Depth 69 mm, height 111 mm. Terminal accepts bidirectional cylinder-lift terminations; tightening torque max 2.8 Nm. Rated insulation voltage 440 V.
