These compact DIN rail mounted protectors guard DIN rail mounted equipment that use an RJ45 style connector. Units install adjacent to the equipment on the same DIN rail or a nearby DIN rail and use less than one inch of rail space. Unit reacts in nanoseconds and causes the surge current to safely flow through it instead of the equipment’s port. Installation is plug-and-play as the ground connection is made through the DIN rail bracket. If the system uses a 19" equipment rack, consider the optional DIN rail mounting system.
