Mersen Surge Protection & Filters
Mersen surge protection and filter products are used to reduce the impact of transient overvoltage, conducted electrical noise, and power disturbances on industrial electrical and electronic systems. In applications such as industrial automation, power distribution, renewable energy, transportation, and data processing, lightning activity, switching surges, and electromagnetic interference can cause equipment disruption or long-term component stress. Properly applied surge protection and filtering helps maintain system availability and supports consistent performance over time.
Mersen surge protective devices (SPDs) work by shunting or clamping transient surge voltage to a safer level before it reaches sensitive loads. These devices are commonly installed at the service entrance, in distribution panels, and within control panels or automation cabinets to protect PLCs, HMIs, power supplies, AC drives, and industrial communications equipment. By limiting transient energy and directing it to an appropriate grounding path, SPDs help reduce the likelihood of nuisance faults, component failure, and unplanned downtime.
Mersen power line filters are used to attenuate conducted electromagnetic interference (EMI) and radio frequency interference (RFI) on power lines. By reducing noise that can disrupt control electronics and communication circuits, filtering helps improve signal integrity and minimize interference-related faults. Together, surge protection and filtering provide a complementary approach to industrial power protection in electrically demanding environments.
FAQs
Q: What are Mersen surge protection devices used for?
