It delivers 100 kA breaking capacity at 400 V AC, dropping to 3 kA at 500 V and 2 kA at 690 V. Ground fault detection is not included — that's handled separately by a residual-current device or an upstream ground-fault relay.
The 45 mm width and 90 mm height keep it to a single DIN module footprint, so it slots into a standard motor starter row without crowding adjacent contactors or overloads. Spring-loaded terminals on both the main and auxiliary circuits accept 2x (0.25 to 2.5 mm²) solid or 2x (0.25 to 1.5 mm²) finely stranded with ferrules. Finger-safe touch protection (IP20 on the front) means the panel builder doesn't need to cover the breaker face separately in a finger-safe enclosure.
