1. Overview
FN5-12R (L) type indoor AC high voltage load switch A fuse combination of electrical appliances for 50HZ, 12KV of the electrical network, as the breaking load current and the use of current. The load switch with fuse can cut off the short circuit current for the protection switch.
The load switch can be equipped with CS6-1 type manual operation mechanism, this product is dedicated to the CS mouth manual or CJ mouth electric operation mechanism.
2. the use of environmental conditions
