The 2-pole form factor breaks both line and neutral, common for single-phase 230 V supplies or as a switched neutral in multi-pole assemblies. The rated short-circuit breaking capacity Icn of 10 kA per IEC 60898 is the service breaking capacity — what it can clear repeatedly under normal duty. The Icu of 25 kA per IEC 60947-2 is the ultimate breaking capacity, a one-shot fault clearance rating. The IP20/IP40 rating means it's protected against solid objects over 12 mm (finger-safe) when installed in a panel; the IP40 faceplate rating adds protection against tools and small wires over 1 mm. This is a panel-mount component, not a standalone enclosure. The 35 mm width occupies two 17.5 mm modular spaces — standard for a 2-pole MCB. The 88 mm height and 69 mm depth fit within a typical 200 mm deep enclosure with clearance for wiring. Terminal tightening torque is 2.8 Nm max for screw-type terminals, which accepts up to 25 mm² conductor. The bi-directional cylinder-lift terminal design allows both busbar and cable entry from either direction without special adapters.","metaTitle":"ABB 2CDS271103R0165 MCB, B-Curve, 16A, 2-Pole, 10kA","metaDescription":"ABB S200 series miniature circuit breaker, 16 A rated, B tripping curve, 2 poles, 10 kA Icn, 25 kA Icu, DIN rail mount, IP20/IP40, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["2-Pole MCB (DIN Rail)"],"specifications":{"Depth":"69 mm","Poles":"2","Width":"35 mm","title":"2CDS271103R0165","Height":"88 mm","IP Rating":"IP20;IP40","description":"Miniature Circuit Breaker, B, 16A, 440V, IP20 / IP40","Mounting Type":"DIN Rail Mount","Rated Current":"16 A","lifecycle_stage":"current","Overvoltage Category":"III","Terminal Contact Type":"Bi-Directional Cylinder Lift","Rated Insulation Voltage":"440 V","Tripping Characteristics":"B","Tightening Torque - Screw-Type Max.":"2.8 Nm","Rated Short-Circuit Breaking Capacity Icn":"10 kA","Rated Short-Circuit Breaking Capacity Icu":"25 kA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$75.37 – $87.14","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/1a963bd5fceef66361105c94b2d8f275.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the key ratings for this MCB?","answer":"Rated current 16 A, B-curve tripping, 2 poles, rated insulation voltage 440 V, Icn 10 kA, Icu 25 kA, overvoltage category III."},{"question":"What is the difference between Icn and Icu on this breaker?","answer":"Icn (10 kA) is the service breaking capacity per IEC 60898 — the fault current the breaker can clear repeatedly during normal operation. Icu (25 kA) per IEC 60947-2 is the ultimate breaking capacity — the maximum fault it can clear once without being replaced. For most commercial panels fed from a transformer under 10 kA fault current, the Icn governs; for industrial distribution with higher prospective fault energy, the Icu provides coordination headroom."},{"question":"What enclosure or mounting does this MCB require?","answer":"DIN rail mount on 35 mm rail per EN 60715.
