The DS2x0-dc surge protectors are designed to protect equipment connected to continuous power supplies. These devices utilize a varistor-based design, with voltage suited to the network. Equipped with thermal disconnectors, they allow for monitoring potential end-of-life conditions. The surge protectors are mounted on a symmetrical rail and connected in parallel to the network they protect.
