The isolating switch N..DC in the special version for up to 1500 VDC can be used as 1- or 2-pole. It meets the isolation requirements for grounded IT networks as well. Accessories such as bridge kits, connection terminals, and door coupling rotary handles allow for individual installation in various distribution systems. Auxiliary switches, voltage triggers, and remote drives enable signaling and automation. Notes: Main switch properties including forced disconnection according to IEC/EN 60204 and VDE 0113. Isolation properties according to IEC/EN 60947-3 and VDE 0660. Connection technology: For 2-pole switching, a series connection according to the specified connection options is required. Switches cannot be combined with plug/retractable technology and/or rear connections. In ungrounded networks over 1000 VDC, the installation must be carried out in such a way that the probability of a double earth fault is negligibly low.
