120 products
External-mount surge protective devices (SPDs) install outside electrical panels or equipment and are used to detect and limit power surges that can damage equipment. These SPDs have visual surge protector status indicators, so users don't need to open the panel to check. They're used in residential, commercial, and industrial applications.
Chase-Nipple External-Mount SPDs
These SPDs are used for service entrance, branch panel, or sensitive electronic applications to detect and limit power surges to protect equipment from damage. They have a chase nipple to terminate the wire in an enclosure. They are mounted externally as close to the service panel as possible.
