This 2-pole unit switches both line and neutral (confirms neutral conductor switching), so it's a straight fit for single-phase circuits where you need full isolation on both poles. The 55 mm installation depth and 2 width units match the standard SENTRON modular footprint — drops into any DIN-rail enclosure without panel modification. Rated for AC/DC voltage and overvoltage category 3, meaning it's designed for fixed-installation distribution boards with transient overvoltages up to 4 kV.
