What this RCBO does on the rail
It combines a 32 A thermal-magnetic trip (C-curve, so it holds 5–10× In for motor inrush and lighting ballast starts) with a 30 mA residual-current detection of Type AC (sinusoidal AC faults only). Rated breaking capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2 — adequate for most domestic and small commercial sub-distribution where the prospective fault current stays under those limits. The 50 Hz operating frequency matches standard mains supply in European and many Asian grids. Temperature derating is published across the full range: at 40 °C ambient it carries 30.4 A, at 50 °C it drops to 28.8 A, and at 70 °C it's down to 24.64 A.
Depth is 77 mm, height 90 mm, installation depth 70 mm. Mounts in any position — no orientation restrictions for the residual-current electronics. IP20 with the distribution board installed and conductors connected; not rated for wet or dusty environments without an enclosure. Halogen-free and silicon-free construction, which matters for clean-room or semiconductor-adjacent installs where outgassing contaminates optics or wafers.
