The B-curve means the magnetic trip operates between 3 and 5 times rated current — 18 to 30 A — so it's sized for resistive and low-inrush loads like lighting circuits, small heaters, or control transformers. The 6 kA Icn (rated short-circuit breaking capacity per EN 60898) and 10 kA Icu (ultimate breaking capacity per IEC 60947-2) give you headroom: Icu is the maximum fault the device can clear once and remain functional, while Icn is the guaranteed breaking capacity for the service life. On a 50 Hz system with overvoltage category III, this RCBO is suited for final sub-distribution in residential or light commercial panels. ## Mounting and enclosure fit The 35 mm width — two module spaces — and 85 mm height fit a standard distribution board. IP20 at the front terminals and IP40 at the enclosure face means it's protected against tools and solid objects over 1 mm; fine for dry indoor panels, but not for washdown or outdoor exposure. Terminal torque spec is 2.8 Nm max — a standard screwdriver setting, no special tooling needed.","metaTitle":"ABB 2CSR255180R1065 RCBO, 6 A, B-Curve, 2-Pole, 6 kA","metaDescription":"ABB 2CSR255180R1065 RCBO, 6 A, B-curve, 2-pole, 6 kA Icn, 10 kA Icu, IP20/IP40, DIN rail.
