P11VNT3 voltage protection rating question

This was originally posted on APC forums on 6/10/2013


On the APC website the Tech Specifications for P11VNT3 only claim "UL 1449 TVSS Rating  330V" On the back of the unit, there is this info: L-N 400V L-G 500V N-G 500V. Could someone explain this discrepancy? Is it a discrepancy? A APC phone support rep merely read to me the info on the website - I pointed out to him that didn't help. He transferred to someone else - who also lacked anymore tech info than what I could see on their website. A Tripp Lite rep told me TVSS is an outmoded rating.

under the Product Overview tab, this bizarre bit of info is provided. Thanks, but I don't think that tells me anything about the P11VNT3. I could be wrong.

"IEEE let-through rating and UL 1449 compliance 

The 'Institute of Electrical and Electronics Engineers' (IEEE) Let-Through Voltage rating is based on a test that subjects a Surge Protector to a 6,000 volt spike. The rating equates to the amount of excess voltage that reaches connected equipment. The lower the number, the better the performance of the Surge Protector is. Underwriter's Laboratory's UL1449 surge protection safety standard uses these ratings to help users gauge performance. UL's best Transient Voltage Surge Suppressor (TVSS) Let-Through Voltage rating is "300V". "

I first learned of this issue an Amazon a user review. We have been buying APC UPS, voltage regulators and surge protectors for years. This issue and the Fail Safe discrepancy I noted in an earlier post http://forums.apc.com/message/48658#48658 has caused us to doubt the accuracy of the info provided by APC; we need that info to make informed buying decisions. I should not have to resort to checking user reviews on Amazon, which is where if first came across the TVSS Rating of 330V versus info printed on the back of the P11VNTS.
