Surge Protective Devices

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.

Current Technology Surge Protection

Select-SL3 Series

Select® SL3™ was the first hybrid design in the market to offer protection to critical loads and downstream equipment from catastrophic overvoltages.

TransGuard-TG3 Series

TransGuard®─TG3™ (TG3) surge protection devices protect and prevent costly downtime and equipment damage caused by routine or catastrophic electrical disturbances.

Panel Extension PX3 - External Mounting

Choose our PX3™ suppression system when you need an externally mounted surge solution that can be physically attached to the top or bottom of any panelboard.
