Product Description
Description of High voltage vacuum load switch FN12-12D/630-20
vacuum circuit breaker
FN12-12D/630-20 series indoor AC high voltage load switches is a rated voltage of 12KV, rated frequency 50Hz three-phase high-voltage switch equipment ,for the closing and opening load current, loop current, air containing transformers and cable charging current, short circuit current of the Closing. Equipped with grounding switch load switch that can withstand short-circuit current.
FN12-12 (R) D/125-31.5 series AC high voltage load switch- fuse combination units, is the FN12-12D load switch and S LAJ-12 (XRNT -10) high-voltage current-limiting type fuse combination units together in the indoor high voltage switchgear. It can be a reliable short-circuit breaking current up to any current; load switch breaking current, the fuse short-circuit breaking current breaking joint working between the current and total short-circuit current of any over-current, fuse through its impact to load switches opening.

Our story with customers
In 2005,we received the email from ALIBABA that a Russian customer would like to order the KYN28-12 indoor metal-clad enclosed switcgear.We confirm the product parameters and pictures carefully again and again with the client,the last communication is the most difficult in price,it is a psychological warfare,customers began to demand a 20% cut,we insist on our price,emphasis on the various advantages of our products with the high quality. After compared with other factory,Russia customer finally chose to coperation with our company.After more than 20 days,customers sent a email to tell us that they are very satisified with the goods.
