About Mersen (formerly Ferraz Shawmut)

Solar Power Circuit Protection

Mersen (formerly Ferraz Shawmut) offers a dedicated range of circuit protection solutions for solar power and wind power generation and distribution systems. Drawing on a century of experience - and an ongoing commitment to critical research in electrical safety in both traditional and emerging markets - we provide solar power designers, engineering specifiers, solar power installers and solar power equipment manufacturers with innovative circuit protection products and unbeatable technical support.

A wide range of circuit protection solutions for solar power generation and distribution.
Generating electricity from solar energy is an extremely reliable process – as long as it’s properly protected! Ferraz Shawmut offers a trusted range of circuit protection solutions that will help protect your solar power investment. Any installation, whether it’s a stand-alone solar array with a back-up generator set or a grid-connected system, is vulnerable to fault currents or lightning.

Today, fuses and surge protective devices are the most effective ways of protecting the wiring and electrical equipment in a Photovoltaic (PV) system. Fuses protect the cables between strings of modules from overcurrent damage. The faulty circuits are isolated allowing the system to continue generating power. But that protection must be designed, dimensioned, tested and adapted to the specific features of solar applications.

At Ferraz Shawmut, we offer a dedicated range of protection components specially designed for solar power generation and distribution including, fuses, fuse holders, wire management solutions, disconnect switches, and surge protective devices.
