Fuses provide short-circuit protection. High safety level during fuses re-placement is provided by the use of disconnector with two fast earthing switches.

Quick and easy replacement of fuses is possible thanks to innovative ejecting mechanism. State of disconnector and earthing switches is indi-cated by auxiliary contacts.
