- The load switch is of frame structure with compact structure. Integrated load switch, fuse, grounding switch as one of the high-performance high-voltage electrical products.
- When the brake is opened, it has obvious isolation fracture, which increases the inner diameter of the compressed air and enhances the arc extinguishing ability compared with similar products, so it has a strong breaking ability.
- There is a mechanical interlock between the load switch and the grounding switch to prevent misoperation.
- There is a transparent cover to close the live static contact (busbar room), and it is absolutely safe to repair or replace the fuse.
- The load switch is equipped with a door lock, which can easily interlock the switch cabinet door with the switch. When the cabinet door is opened or the door lock is unlocked, the load switch cannot be operated. When the grounding switch is not closed, the cabinet door cannot be opened.
