Impossible to tell. It simply connects the wire with the high voltage to the ground tab. Whatever is supplying the current will react however it will react. Some things are current limited some are not.
If too much energy is suppled, it pops the surge suppressor component. But surge suppressors are sacrificial by design.

The old 444 and other radio specific units have HV on the POE pairs and your choice of LV or HV on the data pairs. GigE SS is your choice, LV or HV. GigE SS POE is all HV on all wires. The buyer needs to know that if you want something clamped at 4 volts, it will clamp at 4 volts. And that is the ultimate in protection for non POE situations assuming there isn't a bunch of RF or other noise causing false clamps. If you put 5 volts on the line it will clamp. I am always surprised when people do this and then complain about it. Kinda like airbags going off on a demolition derby car. How is that the fault of the airbag? -----Original Message----- From: George Skorup (Cyber Broadcasting) via Af Sent: Tuesday, December 09, 2014 6:20 PM To: af@afmug.com Subject: Re: [AFMUG] Wrong surge suppressor on gig POE I think all pins or pairs on the non-PoE GigESS's are clamped under 10 volts. So.. boom? Are you sure you didn't get regular 10/100 APC PoE SS's? And that's why your GigE isn't working? I believe the GigESS-HV's are pretty clearly marked/stamped as HV. At least the ones I have in the PRM24 chassis in the NOC are. Yep, just looked, the back of the handle is stamped HV.
