Two-pole design (2P) means it switches both line and neutral on a single-phase circuit, or two phases on a three-phase branch. Width is 36 mm (2 modular units), so it occupies two standard DIN-rail spaces. Mounts in any position — no orientation restrictions in the panel.
Installation depth 70 mm, overall depth 76 mm — standard for SENTRON 5SL family. Sealable (provision for a lead seal) lets the utility or facility lock the handle position.
