Outdoor Single Port Gigabit PoE Ethernet Surge Blocker.


BFR Digital's new series of High-Speed Surge Blocking Devices are designed to protect against faults caused by short circuits, induction and lightning surges. Unlike traditional surge arresters, BFR Digital's Surge Blocking Devices do not need an Earth connection. The Surge Blocking Device will trip in less than 1 microsecond when the surge current reaches 750mA. BFR Digital's Surge Blocking Devices block surges and provide an effective barrier behind which sensitive electronics will not be exposed to large voltages or currents during surge events. After the surge event, the Surge Blocking Device will automatically reset.


Resistively coupled transients cause most of the lightning damage to electronics and electrical equipment. These transients are caused by a difference in potential between two connected electrical earth points.
