Descriere
Switch-disconnectors N..DC in the special version for up to 1500 V DC can be used on 1- or 2 poles. The comply with the isolation properties even for earthed IT networks. Accessories, such as bridge kits, connection terminals and door coupling rotary handles enable individual installation in the most varied of distribution systems. Auxiliary switches, voltage releases and remote operators facilitate signaling and automation. Notes: main switch characteristics including positive drive according to IEC/EN 60204 und VDE 0113. Isolating characteristics according to IEC/EN 60947-3 and VDE 0660 . Terminal type: a series connection is required for 2 pole switching according to the specified connecting possibilities. See accessories bridge kits. Switch can not be combined with plug-in / withdrawable units and / or connection on rear. for non-earthed networks > 1000VDC the installation must be configured such that the likelihood of a double earth fault is negligibly small.
