ABB Surge Protection & Filters
ABB surge protection and filter products are used to protect industrial electrical systems and sensitive electronics from transient overvoltage events, conducted electrical noise, and power disturbances. In industrial automation, manufacturing, utilities, energy, and infrastructure environments, lightning activity, switching surges, and electrical interference can disrupt operation and damage equipment. Surge protection and filtering help maintain system availability, support consistent performance, and reduce unplanned downtime.
ABB surge protective devices (SPDs) limit and divert surge voltages before they reach downstream equipment. They are commonly applied at service entrances, distribution panels, and within control panels or automation enclosures to protect critical assets such as PLCs, HMIs, drives, power supplies, sensors, and industrial communications equipment. By clamping transient events and directing energy to an appropriate grounding path, SPDs help reduce stress on connected electronics and lower the likelihood of component failure.
ABB power line filters are used to reduce conducted electromagnetic interference (EMI) and radio frequency interference (RFI) on power lines, helping minimize interference-related faults in control and automation systems. Many ABB surge protection and filtering solutions are available in compact DIN-rail or panel-mounted formats suited for industrial control environments. When properly selected and installed as part of a coordinated protection strategy, these products help improve long-term reliability of electrical infrastructure and automation systems.
FAQs
