NH Fuse-Links, Fuse-Bases and Fuse-Disconnectors

The NH system is classified among plug-in fuse systems and is composed of:
* fuse-base (possibly including terminal covers and phase barriers)
* fuse-link with blade contact
* fuse-link replacement device (LV HRC fuse puller)
Since the design of this system cannot guarantee non-interchangeability of rated current, it must be handled by a qualified professional.

Mersen NH fuse-links 800VAC was engineered and designed
specifically for photovotaic systems. gS types are full range breaking
capacity fuse-links and are used to protect cables and equipment.
They can interrupt any fault current, from overloads up to their
breaking capacity, and so can be used alone as protection. They are
the perfect solution of protection when used with DC/800VAC Solar
inverters.
This fuse range is offered along with Mersen 800VAC
Fuse-switch-disconnectors, for a complete fuse-system protection.

BSL NH-vertical fuse rails are touch protected IP20. BSL are designed for direct installation on to bus bar systems in triple pole arrangements. BSL size 1 250A, size 2 400A, size 3 630A are available 185 mm bus bar systems. *BSL 250A, 400A, 630A are designed for NH fuse-links in accordance with IEC/EN 60269-2, VDE 0636-2, size 1: 250A, size 2: 400A and size 3: 630A.*The system is a modular system that allows the installation of individual components. BSL offers the user the possibility of fast and easy installation as well as a high degree of protection during installation and maintenance.

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.
