The Corrpro CGI-100 is a solid state GPS interrupter designed to exceed industry requirements for a robust interrupter. This is achieved by utilizing a neoprene thermoplastic gasket within a die-cast aluminum enclosure. The CGI-100 combines advanced microprocessor and semiconductor technology with quality components to achieve an advanced “warm to the touch” enclosure while interrupting up to 100A of current for the Cathodic Protection Industry.
