About On Load Isolator with Fuse Combinations

On Load Isolator with Fuse Combinations

The outdoor On Load Isolator or Load Break Switches contained in the list are meant for the switching of feeder lines and ring mains or transformer feeders in connection with Fuses with tripping arrangement or with indication) for short circuit protection for switching under offload conditions.

They are produced in 6 modules:

1. For Vertical installation

2. For Horizontal installation on lattice towers, concrete or on wooden towers

3. Without fuses

4. In connection with fuses with tripping arrangement & with making capacity

5. In connection with fuses with tripping indication only

6. In connection with Drop Out fuses
