IEC Fuse Switch Disconnectors

The D0 Linocur® is a combination of switch disconnector fuse and Neozed® 63A fuse-link, equiped with significant safety characeristics and sophisticated switching and terminal technology.

The power dissipation of Neozed® fuse-links leads to internal heating in the Linocur® device. Special design measures have been implemented in the development of Linocur® in order to prevent the device from overheating and avoid the unwanted, premature operation of the fuse-link:
- generously sized, solid copper strip conductors
- highly sprung foot contact
- wide area of heat transfer through contact with the screw cap
- wide area of contact at the foot contact
- special contacts which share functions

Thanks to this design, Linocur® features one of the lowest power dissipation values on the market for D0 fuse-combination units devices.

ProGrid NH vertical fuse switch disconnectors are designed for installation to 185mm busbars systems in triple pole arrangements. The installation depth of ProGrid is 150mm.
Thanks to its modular system, the ProGrid solution allows the installation of individual components, it offers the user the possibility of a quick and easy installation as well as a high degree of protection during installation and maintenance with its two-stage opening: in parallel then in rotation, patented by MERSEN.
2 alternative designs are available for a user-friendly installation according to the needs:
- The standard ProGrid fuse switch disconnector to protect the substation from overcurrent and interrupt the electrical circuit’s flow.
- The smart ProGrid fuse switch disconnector to monitor energy flow in addition to its standard functions; the ProGrid solution can be retrofitted from Standard ProGrid to Smart ProGrid also on customer side.
