The P11VNT3 APC Product Overview tab states that
APC Performance SurgeArrest 11 Outlet with Phone (Splitter), Coax and Ethernet Protection, 120V
"Fail Safe Mode
Most other surge suppressors continue to let power through even after their circuits have been damaged, leaving your equipment exposed to future surges. APC's SurgeArrest fail safe, which means that once the circuit of an APC SurgeArrest has been compromised the unit disconnects equipment from the power supply ensuring that no damaging surges reach your equipment."
However the manual states the opposite.
"This device features an internal protection that will disconnect the surge protective component at the end of its useful life but will
maintain power to the load - now unprotected."
This is critical information.
Michael Horowitz, respected tech journalist, criticizes the Tripp Lite surge protector for having this same problem. He says he will stick with the APC NET8 (because of its Fail Safe Mode). I purchased three of the P11VNT3 for the same reason - once surge protection no longer available due to a surge or age of MOVs, no power would be sent to the device attached. That way you know you need to replace the surge protector. (I called Tripp Lite, rep told me that if a surge protector is attached to a refrigerator or server, you would want power to continue being sent even after surge protection in no longer working. I called APC asked about the P11VNT3 regarding this issue, the rep did mention/know that P11VNT3 has the same problem)

"See for yourself, here is a PDF of the Owners Manual for the Tripp Lite Isobar4.
See that box near the top, just above the Installation section . It says
"All models feature an internal protection that will disconnect the surge-protective component at the end of its useful life but will maintain power
to the load - now unprotected." Translation: when the thing dies, your stuff is not protected."
So what's accurate - the website info or the PDF User Manual? I assume the manual. As a side note, neither the APC website nor the NET8 User Guide PDFdocument makes no mention of "Fail Safe Mode"

What is the official word on this? Is the website correct or is the manual correct? The retail box makes no mention of Fail Safe mode.

Thank you so much for posting this bmad. I was on this website researching that contradiction. This "Fail Safe" feature was very important to me, bought an APC P8T3 on the basis of the website statement, then was confused and dismayed to read what seemed to be contrary information right at the beginning of the User's Manual.
