Contact (Moving / Fixed)

Moving contacts are made of electrolytic copper, tin plated in shape knife blade type with self cleaning action during operation, The fixed contact terminals in each phase have separate main and arcing contacts for long contact life / increase of current carrying capacity and to ensure temperature rise with in permissible limits.


Operating Handle & Interlocking

The operating handle is made of steel and is provided on the right hand side of the switch enclosure. Door interlock ensures the door cannot to be opened when the switch is ON position there by providing safety.


Terminal Blocks

Terminal Blocks are made of SMC / DMC which has excellent thermal, mechanical and dielectric properties. Terminal Blocks are provided for cable termination.


Enclosure

The enclosure is powder coated which is made of sheet steel suitable for individual mounting. They are provided with adequate Knockout for cable entry.
