Asking good questions! I'm pretty sure 140V is very low. The APC P10U2 which sells for ~$60 right now on Amazon has a clamping voltage of 330V.




Two important factors to consider:
-Clamping voltage (at what voltage (beyond normal 120V) does the surge protector act)
-Response time (how quickly does the surge protector act to break the circuit)


The faster the surge protector responds, the better (makes sense). The LOWER the clamping voltage, the less potential damage gets caused.


With the APC surge protector, your equipment gets subjected to 330V (albeit for a short period of time) BEFORE the protector kicks in. With the Tripp Lite, the voltage never goes beyond 140V, which seems amazing. Especially considering that many devices we have plugged in these days are multi-voltage (100V-240V). Laptop charger, phone charger, monitors, some TV's, can handle 240V... so if the thing stops at 140V --> amazing. Of course the fridge, the blender, and other devices that are either operating or on standby might not like 330V very much.

I have a "whole house" surge protector installed at the meter base, by the power company, as a primary/external first line of defense. Then I have my desktop, NAS, and expensive crap plugged in to an APC battery backup. You can also buy and install whole-house surge protectors that go in your break box. They provide similar protection to a meter-base device. I also have an APC UPS for the TV + devices (network switch, access point, cripple TV, Blu-Ray player)... and another APC UPS that has the main networking gear plugged in to it (router, controller, primary switch, etc.).


I'm going to pickup at least one of these Tripp-Lite protectors for other sensitive crap that isn't convenient to have plugged in to a battery backup.

Sorry for all of the quotes, but I figured you'd all be interested. I'm not convinced that the clamping voltage is 140V... According to the PDF from Tripp Lite, it's 330V... which may be just fine given the response time ¯\_(ツ)_/¯.

"UL1449 Let Through Rating 330V"


"AC Suppression Joule Rating 3330"


"AC Suppression Response Time NM = 0 ns. CM = <1 ns"



Thought I'd add this:"From the Wirecutter: The best surge protector for your home electronics"

Shame it's from 2016, but was still an interesting read.

1. That would involve purchasing from a pile of garbage like NewEgg (same company who willfully provided customer data to tax authorities when they didn't have to, for starters).


2. It's not sold by NewEgg. It's "Sold and shipped by: Great Gamer". Not NewEgg.

Quote from Eagles89 :
The Versa is actually like $20k for the automatic version. You still proved my point. You are paying 6x for this surge protector when people don't even pay 6x for a Mercedes.

LOL... 6x compared to what? You seem irked by the cost of the surge protector. And you're comparing surge protectors to vehicles, regular consumer vehicles to luxury vehicles (generally speaking).


If you don't want to buy it, don't buy it. It obviously provides sufficient value to people that are willing to pay the price (myself included). As another poster said, Eaton and Tripp-Lite are top-notch. People are free to buy a piece of sh*t surge "protector" from Anker or similar garbage brands. Cheaply built, often not even UL listed, etc. etc. but cheap.


It's like people who buy cheap, 3rd party chargers. "Why would you pay $50 for the Apple 30W USB-C charger???". LOL because whenever there is a teardown of an Apple (or Samsung, etc.) charger next to a cheap one --> the difference is night and day. There's no comparison. An Apple, Samsung, etc. charger is going to be better built. UL Listed. SAFER. Longer lasting. Proper high/low voltage isolation. Proper circuit design. High quality Japanese capacitors. And more.


People are free to buy trash. Some people know better, and they prefer to buy better products. With many things, it's actually cheaper in the long run to buy a more expensive, better built product up front. I have a jigsaw that I bought in 2009. Bosch 1590EVSK, cost me ~$150 back then. Guess what? STILL works today, after years and tons of use. When the power switch failed, I was able to buy a new one easily. You think I could get a new power switch for some piece of sh*t $30 jigsaw 11 years after purchase? Unlikely. A better made product will not only last longer, but will perform better during its life, and will usually be more enjoyable to use.


Don't worry, no-one is forcing you to buy this. And people with the discretionary income to buy a surge protector are not "causing inflation" LOL. Take a look at corporate profits if you want to see a massive driver of inflation (along with other factors, of course). If you don't believe me, go listen to publicly available earnings calls where they have openly admitted as much. Taking advantage of the "inflation" narrative to increase their prices and make massive profits.

Oh and people DO pay 6x for a Mercedes LOL! S-Class starting price? ~$120k (8x). I guess that's contributing to inflation as well, /s.

The UL 1449 standard has several voltage protection rating levels that devices can meet. 330 volts is the lowest voltage rating the standard defines. Devices that meet the 330-volt rating have a clamping voltage of 330 volts or less. So, a device with a 140-volt clamping voltage would have a voltage protection rating of 330 volts according to UL 1449.

Wow nice, thanks for the info, I wasn't aware that 330V is the minimum! Understanding that though, I don't see 140V documented by Tripp-Lite anywhere. I would think they would want to disclose it, as a selling point if anything. Maybe not, who knows.

I found a reference to the 140V on this page:

Belkin sells the same power strip for $10. The only difference is you "only" get $15k insurance instead of $50k insurance. You are mostly just subsidizing other people that file claims on the insurance. The actual product is not worth $58.

You make an interesting point re: subsidizing the insurance lol Smilienod. The cynic in me agrees with that a bit. I still don't agree with you entirely regarding the value proposition, but thanks for the back and forth.

Is Amazon an authorized reseller of Tripp Lite/Eaton?
I asked because someone in previous threads reported that Furman refused to honor warranty when people buy their surge protectors from Amazon.

Edit:
Yes, answering my own question, Amazon is one of their authorized resellers.

They mention the 140-volt clamping voltage on this old datasheet [octopart.com]. The current datasheet [tripplite.com] doesn't mention the clamping voltage. Both datasheets mention the 330-volt UL 1449 rating. The AC suppression joule rating changed between datasheets, so maybe they are using different MOVs now that don't clamp at 140 volts.

Wow! Good to see Tripp Lite is still in business. I have had a couple of these for 20+ years.
Tripp Lite's mainly been selling to the commercial/industrial market all this time.
I usually buy their products for our server room, usually their rackmount surge protectors.

I happen to also own one of these exact Tripp Lite units, also going on 20+ years in 24-7-365 service.

Right, I have a couple old ones that might be from as far back as the 1980's. This is a power filter, with isolation between banks too, not just a simple surge protector.
