Why Do Vertical Fuse Disconnect Switches Require A Custom Shaft Length?

Vertical installation is inherently space-efficient, but in actual projects, busbar spacing, panel thickness, and the position of the operating handle's tip can vary. These variables dictate that the shaft length must match the specific equipment installation requirements. If the shaft is too short, the switch handle may not reliably reach the contact position; if the shaft is too long, it will interfere with the layout of other cabinet components and even affect the force and travel of manual operation. The custom shaft length allows the vertical fuse switch disconnector to fit product installation schemes in vertical space, while also being compatible with different busbar sizes and switch frames.

Another aspect to consider is the coordination of operation between the nhrt40 vertical fuse switch disconnector and the fuse. The geometry of the handle and shaft directly affects the fuse's insertion and removal positions. Adjusting the shaft length for different design schemes can avoid operational errors caused by mechanical deviations.
