HGIS/PASS Combination Switch Circuit Breaker Mechanisms

Product Features

1. Small size and compact structure of the mechanism; stable closing work, high reliability; long mechanical life (up to 10,000 times or more).

2. Adopting the whole cast aluminum alloy mechanism frame, with light quality and good rigidity.

3. The overall design structure is simple; high degree of integration, low number of parts; high transmission efficiency.The transmission link of the mechanism is a two-axis and three-wheel structure, i.e., energy storage shaft, output shaft and ratchet, cam and roller, with small size of components, few intermediate links and high transmission efficiency.

4. High processing precision of spare parts, stable and reliable overall quality. All important parts are CNC machined, bearings are imported, and the mechanism box is made of stainless steel. All these ensure that the mechanism can be operated reliably for more than ten years and the number of operations reaches tens of thousands of
