Internal-Mount SPDs

Internal-mount surge protective devices (SPDs) install inside an electrical panel and are used to detect and limit power surges that can damage equipment. They save space, so no outside wall space is required for wall mounting. These SPDs can protect specific lines and equipment, equipment fed from the panelboard location, or the whole panel.
