DC Switch Disconnectors up to 1500V
Switch-disconnectors N…DC in the special version for up to 1500 V DC can be used on 1 or 2-poles. They 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 signalling and automation.
