This is a DIN-rail-mount device from the ABB System pro M compact series, sized for final-distribution and motor-circuit protection in industrial control panels. The K-curve trips between 10 and 14 times rated current, designed for loads with high inrush — motor starters, transformers, and inductive loads where a B- or C-curve would nuisance-trip on startup. The 25 A rating means it holds the continuous load current while clearing the short-circuit fault up to 15 kA (Icu) at 440 V. Rated short-circuit breaking capacity Icn is 11.2 kA per IEC 60898, while Icu (ultimate breaking capacity per IEC 60947-2) is 15 kA. The 2-pole form factor occupies 35 mm width on the DIN rail — two module widths — and the bi-directional cylinder-lift terminals accept both busbar and cable connections with a max tightening torque of 2.8 Nm. ## IP20 / IP40 Enclosure and Overvoltage Category III Rated IP20 at the front (finger-safe) and IP40 inside the enclosure, this MCB is suited for installation inside a locked panel where dust ingress is limited but washdown is not required. Overvoltage category III means it is designed for fixed-installation distribution boards — not for downstream equipment-level protection. The 69 mm depth fits standard 100 mm deep enclosures without crowding the wiring gutter. The height of 111 mm is consistent with the ABB S200 series footprint, allowing retrofitting into existing rail-mounted layouts without re-drilling the backplane. ## Sourcing and Lifecycle — Current Production Sourced through authorized distribution channels with full chain-of-custody traceability. Pricing and lead time are confirmed at RFQ against your BOM quantity — no stock-holding claim, but the part is a current-production line item with no supply constraints flagged.","metaTitle":"ABB 2CDS272337R0517 2-Pole MCB, K Curve, 25 A, 440 V","metaDescription":"ABB 2CDS272337R0517 miniature circuit breaker, 2-pole, K tripping characteristic, 25 A rated current, 440 V insulation voltage, DIN rail mount.","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":"2CDS272337R0517","Height":"111 mm","IP Rating":"IP20;IP40","description":"Miniature Circuit Breaker, K, 25A, 440V, IP20 / IP40","Mounting Type":"DIN Rail Mount","Rated Current":"25 A","lifecycle_stage":"current","Overvoltage Category":"III","Terminal Contact Type":"Bi-Directional Cylinder Lift","Rated Insulation Voltage":"440 V","Tripping Characteristics":"K","Tightening Torque - Screw-Type Max.":"2.8 Nm","Rated Short-Circuit Breaking Capacity Icn":"11.2 kA","Rated Short-Circuit Breaking Capacity Icu":"15 kA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$148.21 – $156.64","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/e304668e8e270827c4e37a5063a34735.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order 2CDS272337R0517 or check current pricing?","answer":"This ABB MCB is a current-production item sourced through authorized distribution.
