The need for surge protection
Today’s world is full of electronic products and devices that are
susceptible to damage from overvoltage surges.
Whether the cause is static discharge, lightning, or inductive load
switching, overvoltage surges can quickly destroy industrial and
commercial electronics such as computers and industrial controls.
Bussmann series surge protection products help provide power
quality that’s free from damaging surges.
