The C-curve means the magnetic trip operates at 5–10× In (125–250 A), making it suitable for moderate inrush loads like small motors, transformers, or lighting banks where the start-up surge is higher than a resistive load but not extreme. Its rated short-circuit breaking capacity Icn is 6 kA per IEC 60898, while the ultimate breaking capacity Icu reaches 20 kA per IEC 60947-2. The Icu figure is the one that governs fault-withstand in an industrial panel — a 20 kA SCCR at 440 V means the breaker can safely clear a fault up to that level without upstream devices needing to intervene, which simplifies coordination in a distribution board. ## Mounting, enclosure fit, and terminal design The breaker snaps onto a standard DIN rail (EN 60715) and occupies 52.5 mm width (three modular units of 17.5 mm each). The 88 mm height and 69 mm depth fit within a standard distribution board or sub-panel enclosure. IP20 rating applies to the front face (finger-safe), while IP40 is achieved inside the enclosure — the terminals are protected against tools and small wires. The bi-directional cylinder-lift terminal accepts both copper and aluminium conductors up to the rated cross-section, with a maximum tightening torque of 2.8 Nm. ## Compliance and overvoltage category Rated for overvoltage category III (per IEC 60664), this MCB is suitable for fixed installations downstream of the main distribution board — the typical environment for branch-circuit protection in commercial and light industrial panels.","metaTitle":"ABB 2CDS253001R0254 3-Pole MCB, C-Curve, 25 A, 6 kA","metaDescription":"ABB 2CDS253001R0254 3-pole MCB, C-curve, 25 A, 440 V, 6 kA Icn / 20 kA Icu, IP20/IP40, DIN rail.
