Description
The EF version is intended for outdoor installation and EI for indoor installation, so the series covers both open and enclosed substation switchgear. The motor-driven mechanism is powered from DC 110–220 V or AC 230–400 V, so it fits the existing auxiliary supply of the substation. For sites where remote control is not needed, the earthing switch is supplied with a manual mechanism. The device is mounted separately, on its own support or frame, independently of the disconnector.
