The 10 A rated current with C-curve tripping means the breaker holds steady under normal load but trips instantaneously at 5 to 10 times rated current (50–100 A) — the standard choice for motor circuits, transformers, and lighting with moderate inrush. The C-curve avoids nuisance tripping from brief startup surges that a B-curve would catch. Rated short-circuit breaking capacity Icn is 6 kA per the relevant product standard, while the ultimate breaking capacity Icu reaches 10 kA. The Icn figure governs the breaker's rating under the standard duty cycle; Icu tells you the maximum fault it can clear once and still be functional afterward. If your point-of-supply SCCR exceeds 6 kA, you need to check coordination with the upstream device. The rated insulation voltage of 500 V covers standard 230/400 V TN and TT systems with margin. The 35 mm width occupies a single modular unit, so it fits existing distribution board layouts without respacing. Terminal type is listed as Bi-Directional Cylinder Lift, which accepts both cable and pin-type conductors. Tightening torque max is 2.8 Nm — a common value for 10 A terminals; use a torque screwdriver to avoid terminal heating under sustained load.","metaTitle":"ABB 2CSR255180R1104 RCBO, 10A C-Curve, 2-Pole, 6kA Icn","metaDescription":"ABB RCBO circuit breaker, 10A rated current, C tripping curve, 2-pole, 6kA Icn / 10kA Icu breaking capacity, DIN rail mount, IP20/IP40, 50 Hz, overvoltage category III, active prod","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Residual Current Breakers (RCCB/RCBO)"],"specifications":{"Depth":"69 mm","Poles":"2","Width":"35 mm","title":"2CSR255180R1104","Height":"85 mm","Frequency":"50 Hz","IP Rating":"IP20;IP40","description":"RCBO Circuit Breaker 10A III C","Mounting Type":"DIN Rail Mount","Rated Current":"10 A","lifecycle_stage":"current","Overvoltage Category":"III","Terminal Contact Type":"Bi-Directional Cylinder Lift","Rated Insulation Voltage":"500 V","Tripping Characteristics":"C","Tightening Torque - Screw-Type Max.":"2.8 Nm","Rated Short-Circuit Breaking Capacity Icn":"6 kA","Rated Short-Circuit Breaking Capacity Icu":"10 kA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$59.69","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/77c48a7121117653b1bffc53b4164ab9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the key breaking capacity ratings?","answer":"Rated short-circuit breaking capacity Icn is 6 kA, and ultimate breaking capacity Icu is 10 kA.
