PRODUCT INFORMATION
For interior (point-of-use) surge protection, Cooper
Power Systems offers a wide variety of high quality
surge suppressors – our Storm Trapper® ST120 series.
Each product has unique features designed to meet
various connection and equipment needs.
Used in tandem with the Cooper Storm Trapper HE
(catalog section 235-16) or Storm Trapper HSE meter
socket arrester (catalog section 235-17) at the service
entrance, users can achieve reliable “whole-house”
surge protection for home/office electrical equipment.
All ST120 Suppressors provide multi-stage surge
suppression to protect connected equipment from
harmful power surges, while also filtering noise
interference that can damage sensitive electronic
components.

120 VAC wall receptacle.
