Single Port Gigabit PoE Ethernet Surge Blocking Unit, No Earth Connection Needed.

SKU: POE-SBU-01P Category:


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 when the voltage falls below 10volts. This means that the Surge Blocking Device is only compatible with PoE network switches and injectors that feature PoE sensing.

The surge is only detected in one direction, that is from the field cable to the load and no current limiting exists in the reverse direction.
