Surge protection module. Can be used individually or as part of a coordinated application strategy, to protect sensitive electronic equipment, in industrial, commercial and residential locations, from the stress and degradation inflicted by voltage transients. Outstanding surge protection devices divert damaging voltage transients or surges, away from electronic equipment. Transients are diverted away from sensitive micro circuitry, providing protection against catastrophic failure, costly downtime and data disruptions. For use with the following surge panels of 52120-M1 (1), 52120-M2 (1), 52120-CM2 (1), 52120-M2H (1), 52120-M3 (1), 52120-CM3 (1), 52120-7M3 (1), 52120-7MS (1), 52120-7C3 (1), 52120-7CS (1), 52412-DS3 (1), 57120-M3 (1) and 57120-CM3 (1).
