Are you protecting all possible circuits in your application or only the power lines?
Most companies are aware of the need to protect their power lines from the effects of surges generated by lightning strikes (LEMP – Lightning ElectroMagnetic Pulse) or man-made surges caused by switching devices, like circuit breakers or contactors(SEMPs – Switching ElectroMagnetic Pulse).
However a significant number stop there and fail to go one stage further to protect their final loads. This is probably the single biggest cause of production stops in industrial applications today.
