It switches the neutral conductor as well as the phase, which is what the 1P+N designation means: overcurrent protection on the line, switched neutral on the same pole width. For UL 1077 and CSA C22.2 No. 235 it's rated 5 kA, so it's accepted in North American supplementary-protection applications too.
The quick-assembly fastening system and combined terminals top and bottom speed up panel wiring. Mount it in any position; the vibration resistance (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz per IEC 60068-2-6) is good for machine-mounted subpanels.
