K-curve tripping is the key selection parameter here. It sits between B-curve and C-curve on magnetic trip threshold: typically 8–12× rated current for the instantaneous magnetic release. The 6 A rating means it protects a circuit drawing up to 6 A continuous; the K-curve keeps it from nuisance-tripping on the inrush of a small contactor coil or a 50 VA control transformer. Rated short-circuit breaking capacity Icn is 10 kA per IEC 60898-1 — that is the service breaking capacity for the domestic/commercial standard. The Icu (ultimate breaking capacity) is 25 kA per IEC 60947-2, which is the industrial standard. For a panel fed from a transformer with a prospective short-circuit current under 10 kA, the Icn governs; for industrial distribution where the fault level may reach 25 kA, the Icu is the relevant rating. ## Integration into the enclosure DIN rail mount, 35 mm width per pole, so the 2-pole unit occupies 35 mm of rail space. Depth is 69 mm from the rail to the front of the breaker, which fits standard 80 mm deep enclosures with clearance for wiring. Height is 88 mm. The IP20 rating on the front means finger-safe from the front face;","metaTitle":"ABB 2CDS272061R0377 MCB, K-Curve, 6A, 2-Pole, 440V","metaDescription":"ABB 2CDS272061R0377 miniature circuit breaker, K-curve, 6 A rated, 2-pole, 440 V insulation, 10 kA Icn, 25 kA Icu.
