The 25 A rated current (at 30 °C, per) and B-curve tripping characteristic mean this RCBO is sized for general-purpose loads with modest inrush — lighting, small appliances, and socket circuits. Type A is the minimum requirement under IEC 60364 for circuits supplying single-phase rectified equipment.
The supply connection can be made from either the top or bottom. Depth is 77 mm (70 mm installation depth), which clears most standard enclosure backplates. IP20 rated with conductors connected, so it is intended for enclosed panel use.
Ambient temperature range spans -40 °C to +75 °C, with rated current derating applied above 30 °C: 0.95 A at 40 °C, 0.93 A at 45 °C, 0.9 A at 50 °C, 0.87 A at 55 °C. This derating curve is critical for panel builders when grouping multiple RCBOs in a confined space — thermal accumulation can reduce the effective rating below the marked 25 A.
