M50 series: AC SURGE PROTECTORS HARD-WIRED UNITS AND COMBINER BOXES

M50 series surge protection devices in metal enclosures belong to a complete family of surge protection devices specifically designed to meet the requirements of the North American surge protection standards: USA and Canada. Respectively, the UL1449 ed4 standard and the C22.2 No.269.1–22.2 No.269.5 standards.
They are available in all single, dual or three phase configurations and are equipped with various diagnostic options. Housed in a NEMA 6 metal enclosures, the protection circuit is based on a combination of high energy varistors and GSG to provide a very high discharge current capability. Manufactured in accordance with the UL1449 standard, the safe operation is ensured by real time diagnostics including fault indicators (LEDs), an audible alarm.
