  • Product Description

FN5 12RD(L) Indoor AC H.V.Load Switch

FN5 12RD(L) Indoor AC H.V.Load Switch  It is designed and developed by our own company by

bringing in international advanced technology,considering our own country’s specific power supply.

It performances meet IEC420 AC H.V. Load Switch with Fuse(1990 Edition) and GB3840 3-63kV AC H.V.

Load Switch after strict test and long – time operating. Compared to the product of the kind in the foreign country

its technical parameter has reached the international level with the featrues of small volume and light weight.can

be used in package substation and ring network cebin. It is used widely in 12kV distribution network to protect

the equipment against working wihout phase. The success of the product fills the domestic gap, with functions of switch

isolating and earthing.

1. Quality assurance: All the products will go through lots of tests carefully before dispatch:

Raw material check, Assemble test, Painting check, Nameplate check and routine tests.

2. Competitive production capacity: monthly production more than 1200 sets .

3. Manufactuer’s price: Factory direct sale, most competitive price..
