    MCCB Highlights

    DC MCCB based Switch Disconnectors WLM7DC are used as a main switch in all kinds of DC applications. Thanks to theirs polarity independence can be used also for PV. They serve there as a main disconnector of DC side of the power plant in combiner or array boxes. These switch disconnectors have same size and design as standard WLM7DC MCCBs. Therefore is there possibility to use fully compatible range of external and internal accessories including extended rotary handles, auxiliary contacts, tripping units, motor operators and terminal covers.
