Load-break switches N..DC in the special version for up to 1500VDC can be used with 1 or 2 poles. They also meet the isolating properties for earthed IT networks. Accessories such as bridge kits, connection terminals and door coupling rotary handles allow individual installation in a wide variety of distribution systems. Auxiliary switches, voltage releases and remote drives enable signaling and automation. Notes: Main switch properties including positive operation in accordance with IEC/EN 60204 and 0113. Disconnector properties in accordance with IEC/EN 60947-3 and 0660. Connection technology: For 2-pole switching, a series connection is required in accordance with the specified connection options. See accessories bridge kits. Switches cannot be combined with plug-in/withdrawable technology and/or rear connection. For unearthed networks > 1000VDC, install in such a way that the probability of a double earth fault is negligible.
