Product Description

FN7-12 High Voltage Indoor Vacuum Load switch with switcgear



1. The type FN7-12RD high voltage indoor vacuum load switch and electrical comination is use for Three phase alternating current Concurrent 50HZ industrial power euipments , its can laod control and protect short current . Load switch is open-close load , closed current , and charging cables current . Electrical comination can close any current . There can be use by hand and power .


2. FN7-12RD is designed by drive type , light weight .


3. The full name of the air switch is the air type low-voltage circuit breaker which belongs to the circuit breaker.

It's called an air low-voltage circuit breaker or air switch because it's done by using air as a medium.
The isolation switch is a kind of high voltage switch electrical appliance mainly used in high voltage circuit .


4. A switching device capable of breaking and carrying current under normal loop conditions and of carrying and breaking current under abnormal loop conditions within a specified time.
It has the function of overload, short circuit and undervoltage protection, and has the ability to protect the line and power supply.
