Where it fits and how it connects
The 45 mm width and 58 mm height fit the compact TeSys K footprint — three of these side by side take about 135 mm of DIN rail, leaving room for a terminal block or a small PLC in a standard 400 mm enclosure. Screw clamp terminals accept 1.5 to 4 mm² solid or 0.75 to 4 mm² flexible, with a tightening torque of 0.8 to 1.3 N·m using a No. 2 Phillips or Pozidriv. IP2X finger protection per VDE 0106 means it's safe for open-panel use where operators might reach near the terminals, though it's not sealed against dust or moisture — keep it inside a cabinet rated to the environment.
