Rated 10 A at 230/240 VAC with a B tripping characteristic, it handles general-purpose lighting and receptacle circuits where fast magnetic trip is needed for short-circuit protection.
Type AC fault-current detection covers sinusoidal AC residual currents, which is the standard for general-purpose circuits without electronic loads generating pulsed DC faults. Thermal derating is published: 10 A at 30 °C, 9.4 A at 40 °C, 8.7 A at 50 °C, and 8.4 A at 55 °C.
Width is 18 mm (1 width unit), depth 77 mm, height 90 mm. Installation depth 70 mm. Mounts in any position on standard DIN rail. Supply connects from below (bottom feed). Touch protection is built in. The part is silicon-free, which matters for potting or conformal-coating compatibility in harsh environments.
