FKRN12-12D Indoor 12kV Pneumatic Load Break Switch with Fuse Combination
The FKRN12-12D is an indoor 12kV pneumatic load break switch combined with a high-voltage fuse and earthing switch. It switches normal load current and, together with the fuse, provides transformer, cable and distribution-circuit protection.
FKRN12-12D Indoor Pneumatic Load Break Switch and Fuse Combination
The FKRN12-12D combines a 12kV indoor load break switch, high-voltage fuse and earthing switch in one compact assembly. The load break switch controls normal load current, while the fuse interrupts fault current and can trigger automatic opening to help prevent single-phase operation.
