Product Series Information
The Crouse-Hinds series MTL SD range is a series of surge protection devices combining 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 exceptionally high packing densities are the consequence of an ultra-slim footprint for individual modules which can thus "double-up" as feedback terminals. Each module provides full hybrid surge protection for 2 and 3 wire loop protection.
