Ensto launches a new pole fuse switch disconnector family

The originally proven design of  Ensto pole fuse switches has been further improved. Now the new fuse

switch family can be operated from the ground by using the operating rod. The SZ160 family will replace the existing pole fuse switch disconnector models SZ50-SZ150, which have been sold and installed hundreds of thousands pieces all over the world. Products are designed in Finland and they last from father to son - and even longer.

The products are used for protecting stranded overhead cables and underground cables in low voltage networks.


Benefits of new range:

  • Safe and easy to install
  • Separate terminal covers
  • Operating stick
  • Suitable for extreme conditions
  • Type tested
  • Laser marking
  • Robust locking mechanism.
