Key features & benefits

MERSEN Smart monitoring solution is key to answer to new challenges of the electrical power grid!
The development of smart Low voltage grids will enable better understanding of the behavior of local LV networks in the context of decentralization and volatility of renewable power sources and of EV charging stations, among others.
Instant monitoring of the network values and status allows a more efficient load & demand management and higher network availability.
Critical or heavily loaded network sections can then be specifically monitored to perform preventive maintenance and high service continuity.
The most user-friendly and most compatible smart monitoring module for NH vertical fuse switch disconnectors !
The compact module designed by Mersen is by far the simplest to install monitoring device and adapts perfectly to the Multivert i-Xtensio ranges that are available today.
The product has been engineered to be fully compatible with Energy Monitoring systems existing on the market and has a very compact design for tremendous functionalities.
This device makes the data available for the end-user that can connect directly on the Modbus modules. The modules measures relevant data directly on the fuse switch disconnector and enables the users to access instantaneously to main data of energy consumption.
