1, Use invention patented technology, the arc extinguishing conduction time of the no-arc device is less than 10 milliseconds.
2, The electrical lifetime is 10~1000 times of normal relays and contactors, greatly reducing maintenance and improve system reliability.
3, Built-in mechanical switch is welded, compared with the plug type relay structure, line loss reduce is above 50%, withstanding surge current is more larger.
4, The current zero-crossing breaking, no breaking over-voltage.
5, Small size, light weight.
