ABB Surge Protective Devices. Learn about the different types of SPDs and the protection they provide.

TVSS guard against transient overvoltages, sometimes call transients, spikes or surges, hence the name Transient Voltage Surge Suppressor or TVSS. Transients are known to damage sensitive electronic equipment in homes, schools, commercial, industrial, and medical facilities, wastewater treatment plants, factories, etc..

ABB offers the most comprehensive portfolio of Type 1 and Type 2 surge protective devices that can be externally or internally mounted. They help reduce costly downtime while protecting sensitive electronic equipment against damaging effects of transients caused by lightning, utility load switching, internal load switching, and more.
