FN7-12 High Voltage Indoor Vacuum Load switch with switcgear
1. The type FN5-12R(L) high voltage indoor vacuum load switch and electrical comination is use for Three phase alternating current Concurrent 50HZ industrial power euipments , its can load 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. FN5-12R(L) is designed by drive type , light weight .
3. FN5-12R(L) is standard by GB3804 and IEC420 .
4. 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 .
5. A load switch is an electrical switch between an isolation switch and a circuit breaker. It has a simple arc extinguishing device that can cut the rated load current and a certain overload current, but can not cut the short circuit current.
