Product range overview
Transient overvoltages can reach electronic equipment via any of the conducting lines which are connected to the equipment. If you don't protect ALL electrically conductive routes into your system, you will be susceptible to the devastating effects caused by transient overvoltages.

Special products
The Furse ESP range is comprehensive and can offer an effective protection solution to the majority of applications.
