	YOU HAVE NOT SPECIFIED THE VOLATGE. 1.FOR VOLATGES ABOVE 66kv SF6 CIRCUIT BREAKER WHETHER THIS MAY BE AIS OR GIS AS PER APPLICATION DEMAND. 2.FOR VOLATGES 66KV AND BELOW UPTO 11KV FOR OUTDOOR APPLICATION SF6 OUTDOOR TYPE IS APPLIED. 3.FROM 66KV-3.3KV INDOOR APPLICATION SF6 CB IS APPLIED. 4.FROM 33KV -3.3KV INDOOR APPLICATION VACCUM CIRCUIT BREAKER IS USED. VACCUM CIRCUIT BREAKER IS AVAILABLE UPTO 33KV,SF6CKT BREAKER IS AVAILABLE FROM 3.3KV TO 765KV

	Dear Guest, Your answer is good. But gone to off topic. I think it is due to you used CAPITAL letters. Please rectify it from the next post.

	What may be the trafo size,voltage,indoor or out door, frequency of switching, nature of load serviced.Air break cb may be the best choice followed by sf6.But that is over simplification for purpose of simple understanding. __________________ Better not count the cent if the risk is many many dollars.

	Shaik.thameem, Unfortunately, your question is so general that a thoughtful answer is unlikely to be given, The posts from Guest and others agree that more information would be very helpful if you want a good answer. For general design information, took at the on-line engineering design data from any of the major suppliers of the circuit breakers. Depending on the voltages, location (indoors, outdoors), current, and environment, one design or another may be more suitable for your application. --JMM

	It is just off topic but I like to use this forum as I am observing a lot of People from middle east are using this forum and making life miserable for others if they have guts please respect knowledge . "Once there was a lion who was in his country zoo having a good meal life .once there was a oil middle east sheikh visited the zoo .The organizers proudly show the lion to oil middle east sheikh . The oil middle east sheikh liked the lion very much and the other lions said to lion you are lucky they are taking you to best place it will be like heaven .The lion felt proud and finally the oil middle east sheikh gave a large amount of money and transfer it to Middle east ZOO .1^st day they give him bananas 2^nd day he got bananas third day things difficult for him he was dying with hunger he shouted at the zoo guys "WHY ARE YOU GIVING ME BANANAS DONT YOU KNOW WHAT A LION EAT " the attendant replied --please note it – "YOU ARE ON A MONKEY VISA SO SOLONG AS YOUR VISA IS YOU ARE A MONKEY " "---Moral of story please check your visa before travel to middle east may be they give you a monkey visa . Please please please they are making life a hell for expatraites and if you are thinking to support them think twice Ferth
