Ethernet LANs are highly vulnerable to the harmful effects of data line transient surges: Lightning strikes, induced voltages from elevator motors and florescent lights, static discharges and even the normal functioning of UPS devices can all pose a threat to Ethernet data and hardware.

The Patton EPG Model 534 uses Silicon Avalanche Diode technology, so performance won't degrade with repeated "hits". Special solid state hybrid circuitry allows the Model 534 to operate transparently, without degrading the performance of the 802.3 network. In fact, multiple protectors may be added to the network without noticeable loss of performance. If the Model 534 should encounter a severe surge (above its rated capacity of 600 Watts per wire), it will send all signals to ground as it fails, thereby “sacrificing itself” to protect the network. You simply replace the protector–instead of having to replace hundreds of dollars in network hardware!
