Product Description

FZN64 high-voltage load switch is a kind of function between high voltage circuit breaker and high voltage isolation switch electric appliances, high voltage load switch is often used with high voltage fuse series; Used to control the power transformer. High voltage load switch has a simple arc extinguishing device, because it can break a certain load current and load current. But it can’t disconnect short-circuit current, so it generally used with high voltage fuse series, with the help of a fuse for short circuit protection.

1. The vacuum bubble is installed in the epoxy resin insulation cylinder, and the insulation performance is stable.

2. There are obvious breaking points and high breaking capacity.

3. The isolation knife is mechanically interlocked with the load switch and the cabinet door.

4. The novel interlocking mechanism of the cabinet door lock automatically meets the requirements of “five preventions”.

5. H-type high breaking vacuum switch can break 20kA short-circuit current. With the protection device, various protection functions can be realized.
