PRODUCT DESCRIPTION

MTL SD55X MTL SD range safe surge protectors.


MTL Surge Technologies has operationally tested the recommended SD range with representative highways listed but no formal approval for their use in systems by the respective bodies has been sought.


The SD range is a series of surge protection devices combine unparalleled packing densities, application versatility, proven reliable hybrid circuitry, simple installation and optional ‘loop disconnect’ facilities – features which make the range the ultimate

surge protection solution for process equipment, I/O systems and communications networks.


The MTL SD modular range takes the established SD range of high performance surge protectors for I/O and introduces a replaceable

element. Maintaining the unrivalled packing density and field proven hybrid circuit design the modular range makes maintenance easy, enabling the replacement of surge protection modules without disconnecting the loop.
