3 phase isolators

[les hanslip]

New at this game and still learning.Need a bit of help on 3 phase please? What is the most suitable device for isolating all live conductors in a 3 phase installation? Any help will be appreciated. les

how about a 3 phase 4 pole rotary isolator? I am also new to this but this is what I would suggest.

Best form of isolators for Three phase supplys is an isolator that isolates all three phases and neutral. Known as TP&N for short. There rotary ones....

Depending on what you are isolating will naturally effect the isolator the two above are 32A but you might need more for some equipment.

Remeber an isolator is designed to dissconnect all electrical conductors from the the supply. (Not including Earth)AND is there to isolate the equipement not to be used as a control device. You should not operate the isolator under load conditions.
