Rated 10 A with a 30 mA fault-current trip threshold, it is sized for final subcircuits supplying socket outlets or small loads where both short-circuit and personnel protection are required. The 30 mA sensitivity is the standard threshold for supplementary protection against direct contact in residential and commercial installations (IEC 60364). The 500 V rated insulation voltage gives headroom on 400 V three-phase systems where phase-to-phase voltage appears across the device in a fault condition. The 2-module width (35 mm) and 85 mm height fit standard enclosure cutouts; depth of 69 mm clears most 80 mm-deep enclosures.","metaTitle":"ABB 2CSR255188R1104 RCBO, 10 A, 30 mA, Type C, 2-Pole","metaDescription":"ABB 2CSR255188R1104 residual current circuit breaker, 10 A rated current, 30 mA fault current, type C trip curve, 2 poles, 6 kA Icn, DIN rail mount, IP20/IP40.","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":"2CSR255188R1104","Height":"85 mm","IP Rating":"IP20;IP40","description":"Residual Current Circuit Breaker, 2 Poles, 10A, 500V","Mounting Type":"DIN Rail Mount","Rated Current":"10 A","lifecycle_stage":"current","Overvoltage Category":"III","Terminal Contact Type":"Screw","Tripping Fault Current":"30 mA","Rated Insulation Voltage":"500 V","Tripping Characteristics":"C","Rated Short-Circuit Breaking Capacity Icn":"6 kA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$243.60 – $252.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/74f9cb0960945081ae987411b359759d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the rated short-circuit breaking capacity of this RCBO?","answer":"The rated short-circuit breaking capacity Icn is 6 kA.
