What you're looking at
The integrated earth-leakage protection means you don't need a separate RCD downstream; this one module handles both thermal-magnetic trip and ground-fault detection.
The 1P+N configuration switches the phase and disconnects the neutral, but the neutral pole is not overcurrent-protected — it's a switched neutral. That's typical for single-phase final circuits where the neutral is bonded at the origin. The neutral sits on the left side of the module, with a 9 mm pitch between phase and neutral terminals, so your busbar or wiring plan needs to account for that offset. The IP40 rating on the modular enclosure face means it's splash-proof from the front once installed in a board.
Clip-on mounting to a standard DIN rail. Depth is 77.5 mm, height 81 mm. Tunnel-type terminals top and bottom accept 0.75–16 mm² rigid or 0.33–10 mm² flexible (with or without ferrule). Strip length 15 mm.
