The ESP-100-POE is a lightning/surge suppressor designed to protect ethernet signals and/or POE signals from the damaging effects of electrical surges.




The Laird ESP series of surge protectors provide a high level of protection against power surges caused by lightning and other causes. These surge protectors are used to protect expensive equipment from damage caused by electrical surges. They should be mounted as close to the protected equipment as possible.

All metal cast aluminum enclosure and shielded RJ45 connectors provide for good EMI noise suppression. The integral mounting feet can be screwed to a metal chassis to provide proper grounding or as an alternative, there is an integral ground wire provided which can be connected to a ground for those systems that require a single point ground connection. These aurge supressors are designed to be used indoors or outdoors (if inside a waterproof enclosure). The ESP -100-POE are compatible with 100Mbps data and 48V POE systems. Protection is provided on all 8 ethernet pins (7.5V clamping on Data pins 1,2,3,6 and 70V clamping on POE pins 4,5,7,8).
