La description
FN7-12DR is used in tri-phase AC power network of AC 50Hz, rated voltage 12kv for breaking load current and controling short circuit current.
FN7(C)-12 type H.V. load switch and fuse box is based on the FN7-12 series H.V. load switch with operating mechanism, making the installation more simpler.
