Protistor® size 36x127 gR (GRB/C), 1000VDC
Mersen DC offers provide a very high performant protection for railway power and auxiliary circuits. Mersen DC Semiconductor fuse-links were developed to provide improved performance required by today's new DC equipment. These fuse-links are typically operated at more elevated temperature than other fuse type, have lower I²t to minimize damage to protected components on short circuits, lower watts loss and longer life.

ProGrid Size 3, 630A 690V, 315A 800V
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.
