MDS series: AC SURGE PROTECTORS AND FILTER HARD-WIRED UNITS AND COMBINER BOXES
MDS 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.
These units are based on the use of modular surge protectors like the DS Series. They are equipped with surge protection and an EMI/RFI filtering option.
They are available in all single, dual or three phase configurations and are equipped with various diagnostic options. Housed in a NEMA 4 metal enclosures, these surge protectors are available in various surge capacities (Imax = 300, 600 and 750 kA). Manufactured in accordance with the UL1449 standard, the safe operation is ensured by real-time diagnostics including fault indicators (LEDs), an audible alarm, and remote signal contacts.
