Construction

The switch is versatile and ideally suited for top mounting directly to poles, transformers and cross arms.

The fuse switch disconnector is fully insulated made from corrosion proof, impact resistant, weather and UV resilient glass fibre reinforced polyamide compound with high glass content.

This high quality of material, together with robust construction guarantees consistent performance even under adverse climatic conditions.

The upper housing of the switch is hinged to the lower body and houses the conductors, terminals and contacts. The operation of the switch is simple and safe with the help of an insulated operating rod.

The fuse contacts are fully shrouded and terminals are made of ETP grade high conductivity copper. They are duly tin plated which ensures minimum contact resistance besides offering flexibility to use copper or aluminum cables.

The switch can take conductor size of 50 to 240 sq. mm
