Breaking capacity is 4.5 kA per EN 60898 (the residential/commercial standard) and 15 kA per IEC 60947-2 (the industrial standard) — the higher figure means it can be applied in an industrial sub-distribution board where fault current potential is higher, as long as the upstream device coordinates to keep let-through within the 15 kA rating. Operating temperature range spans -40 °C to 75 °C, with a derating curve applied above 30 °C: at 40 °C the continuous rating drops to 15.2 A, at 50 °C to 14.4 A, and at 70 °C to 12.32 A — a critical consideration for sealed enclosures or high-ambient locations like a pump house or rooftop panel. Mounting position is unrestricted — the RCBO can be installed horizontally or vertically without derating the thermal-magnetic trip curve, simplifying panel layout. Supply can enter from either top or bottom, and the device is halogen-free and silicon-free — important for environments sensitive to outgassing, such as clean rooms or aerospace assembly.
Where it goes — deployment context
IP20 rated with conductors connected and the board closed — it is not a standalone outdoor device; it belongs inside a weatherproof enclosure if installed in a damp or dusty environment.
