Product Details

The Fuse Cutout type OEI was developed to operate in overhead distribution systems rated at 11
kV to 38 kV grounded systems with 100 or 200 A nominal currents.
Especially designed to protect transformers, capacitors, cables or lines.
It is robust construction, made of rigorously tested material, will interrupt all faults under the
most severe conditions, maintaining mechanical and electric characteristics.
The inserts, hardware and structural bolts and nuts are made from heavy galvanized steel.
The Fuse Cutout type OEI can be applied on all three-phase system rated at or below the maximum
operational rating of the cutout.
