    Note:?The FG type load break switch (disconnect switch) is equipped with stored energy released?by fuse strike pins. The stored energy mechanism for the opening operation is released by fuse?strike pins. The trip actuator is mounted on top of the fuse contact clip.?The DIN type fuse is held in spring type contacts, secured by a tail lever. All the components are?made of stainless steel, to prevent corrosion, have long live, and in the reset position. The trip?lever is parked in an over-centre position.
