The C-curve means it trips between 5 and 10 times rated current — designed for moderate inrush loads like small motors, transformers, and lighting circuits where a B-curve would nuisance-trip on startup, but the fault clearance is still fast enough for branch protection. Rated short-circuit breaking capacity is 10 kA per IEC 60898 (Icn) and 25 kA per IEC 60947-2 (Icu). The Icn figure governs domestic/commercial distribution boards; the higher Icu applies when the breaker is used in industrial panels per the product standard. Either way, it clears a hard fault up to that level without welding the contacts or cascading upstream. Overvoltage category III means it is rated for fixed installation downstream of the main distribution board — not for plug-in equipment. Mounts on standard DIN rail (35 mm per EN 60715). The 35 mm width (2 module spaces) fits the standard cutout in any DIN-rail enclosure. IP20 on the terminals, IP40 on the front face; suitable for clean, dry indoor panels where no washdown or dust ingress is expected.","metaTitle":"ABB 2CDS271103R0164 MCB, 2-Pole C-Curve 16 A, 10 kA","metaDescription":"ABB 2CDS271103R0164 miniature circuit breaker, 2-pole, C-curve, 16 A rated current, 10 kA Icn, 25 kA Icu, 440 V insulation voltage, DIN rail mount, IP20/IP40.
