Our products prevent the destruction of industrial and commercial electrical equipment, ensure an uninterrupted power supply, and help to stabilize the electrical network.

This function is performed by industrial fuses and all related accessories (to prevent short circuits) and by surge protection devices (to protect against damage from power surges).

Our range of solutions and products are designed to perform power conversion. 

Power conversion changes the nature, voltage, intensity or frequency of the current to meet very diverse applications, such as motor speed variation and the transformation of solar and wind energy.

To perform this function, Mersen designs special cooling devices, bus bars and fuses that are integrated around power electronics components.
