Structural Analysis Of Vertical Fuse Disconnect Switches In Multi-current Level Coverage Design

Based on a unified mechanical frame, the vertical fuse switch disconnector series can accommodate rated currents ranging from tens to hundreds of amperes, achieving versatility across different load conditions within the same product series. Product series already on the market demonstrate coverage from 100A to 630A.

Its structural design focuses on modularization of key components such as busbar dimensions, contact travel, and connection terminals. Busbar cross-sections vary across series models according to current ratings, and the vertical installation method facilitates a neat layout and clear path within the distribution cabinet. Standardized fuse specifications are used internally, meaning that when changing the current rating, only the fuse element needs to be replaced or the busbar cross-section adjusted, without replacing the entire nhrt40 vertical fuse switch disconnector series.
