Product overview
Using a vacuum arc extinguishing chamber, air insulation, and an electric spring operating mechanism, the product has strong arc extinguishing ability, many short-circuit opening times, no fire and explosion hazard, and is easy to operate. It is a performance
Excellent, practical product.
The overall structure of this product adopts a three-phase common box type, with casings in and out, dry air inside the box, and an electric spring operating mechanism arranged on the side of the box, which can be used reliably under harsh environmental conditions.
The vacuum arc extinguishing chamber of this product adopts a ceramic shell, a cup-shaped longitudinal magnetic field contact structure, and copper-chromium contact materials. It has excellent breaking and closing short-circuit current capabilities.
This product is small in size, light in weight and beautiful in appearance. The vacuum arc extinguisher and insulating support sleeve are compact in design. The outlet conductive rod is injected with silicone rubber and can adapt to harsh climate conditions and dirty environments.
