mainMain features:
- 300A contact switching capability, compact size; 
- Having a set of bridge type normally open contacts, the contact circuit has "+" and "-" polarities; 
- Coil with energy-saving device, maintaining a maximum power consumption of 4.5W; 
- Adopting ceramic brazing technology, the contact part is sealed and filled with hydrogen gas, and the contact will not oxidize, which can quickly cut off the DC high voltage; 
- Application scope: Telecommunications equipment, solar energy systems, engineering machinery, electric vehicles, electric cars, charging stations, trains, ships, uninterruptible power supply and other electronic control systems;
