Breaking capacity is 6 kA per EN 60898 and 10 kA per IEC 60947-2, so it coordinates with most domestic and light commercial distribution boards where the prospective fault current stays under those limits.
The 10 A rating holds at 30 °C ambient; at 40 °C it derates to 9.4 A, at 50 °C to 8.8 A, and at 60 °C to 8.1 A. The 18 mm width (1 modular unit) fits standard DIN-rail enclosures; installation depth is 70 mm, overall depth 77 mm. IP20 applies once the distribution board is installed with conductors connected.
