The breaker is rated for 400 V AC and 60 V DC, with a breaking capacity of 10 kA according to EN 60898 and 15 kA according to IEC 60947-2.
Rated insulation voltage (Ui) is 440 V AC, which exceeds the rated operating voltage of 400 V AC. This means the breaker's internal clearances and creepage distances are designed for a 440 V system, providing a safety margin in 400 V networks. The IP20 rating applies with connected conductors; IP40 in the handle range means the toggle area is protected against tools and fingers but the terminals need to be inside an enclosure. The 70 mm depth and 90 mm height are standard for this class — it fits existing SENTRON or third-party distribution boards without clearance issues.
The 18 mm width (1 MW) means it occupies one slot in a distribution board — straightforward to swap in or add to an existing row. The neutral conductor is not switched, so this is a line-only pole; pair it with a separate neutral bar or a 2-pole variant if you need neutral isolation. Vibration resistance is specified at 50 m/s² from 25 to 150 Hz and 60 m/s² at 35 Hz for 4 seconds — adequate for installation on machine-mounted panels or near rotating equipment, but not a heavy-industrial shock spec.
