Modern industry relies heavily on electronic automation to increase productivity, ensure safety and provide economic benefits. However, power circuits are often severely polluted with electrical disturbances from switching of electrical loads, electrical noise and even the occasional induced impulse. Since the safety and economic consequences of temporary or permanent failure of industrial equipment cannot be tolerated, protection devices should be installed on critical power circuits. nVent ERICO offers a complete line of surge protection devices that can be coordinated into an effectively staged electrical protection plan. The first stage of defense is the installation of primary protection devices at the mains supply service entrance, followed by secondary protection at distribution branch panels and where necessary, at point-of-use applications.

Surge protection products are designed to help protect against damaging electrical surges on power and communications lines caused by lightning and other switching events. With the increasing focus on system reliability and the Smart Grid initiatives underway in many countries, surge protection is more critical than ever based on the amount of electronics control and monitoring systems on the power grid today.
