Lockable Structure Design Of Vertical Fuse Disconnector

The design of vertical fuse switch disconnector allows for the installation of a locking device in the off position of the switch. This design, using padlocks or similar means to secure the operating handle, is recognized by many engineering standards in electrical equipment maintenance.

The vertical orientation of nhrt40 vertical fuse switch disconnector makes the operating space more compact and also facilitates mechanical locking when disconnected. The locking function is usually directly linked to the handle position and can only be installed in the open position. This design stems from the requirements of international EE standards for locking isolators, helping field personnel to clearly see the open position and supporting standardized maintenance procedures.
