It Finally Arrived
It took several weeks after we published Let's Take a Trip Inside a Power Strip! to line up a modern equivalent, which we'd use for a follow-up tear-down. But it's here now. Hidden somewhere under this ocean of bubble-wrap is the star of today's show. While I dig it out, you may want to revisit my exploration of APC's old SurgeArrest power strip, the company's thoughtful response to my coverage, and a deconstruction of its BX1000 uninterruptible power supply in Tear-Down: Let's Take a Trip Inside A UPS; I'll be referring back to both features throughout today's piece.
The packaging's front side provides a succinct summary of the bar's key features and a photograph showing all of the major visual and functional aspects. About 3kJ of surge suppression and a $300,000 protection guarantee sound fairly good. But exactly what goes on behind the scenes to give APC so much confidence? We shall find out when we get inside.
Wall Of Text
The marketing department went wild on the back side, giving potential buyers a walk-through of each feature listed on the front. On the bottom-left, we see a RoHS compliance declaration followed by the surge protection evaluation method and a list of package contents. At the bottom-right, we have the original owner's equipment protection policy summary, followed by the French translation of surge testing and box contents.
APC omitted headings on the English side. When I do translations, I obsess over making layouts match exactly whenever possible, relatively minor discrepancies like that jump out at me more than they should.
Table Of Contents
Included with the modern SurgeArrest are a user manual, equipment protection policy, a pair of APC-branded cable ties instead of its predecessor's plastic clip, a gold-plated RG6 cable instead of the former's plain RG59, a telephone cable and, of course, the power bar itself.
Old Versus New
As I mentioned in my original SurgeArrest tear-down, I happen to own three of the old-school models. One was opened for repair after a trace blew up. I used the second one for my tear-down story two months ago. And I'm opening the third for a side-by-side comparison of new versus old.
Let's start with the front's unchanged features (at least as far as the exterior is concerned):
- you get the same eleven outlets with exactly the same layout
- the same three indicator LEDs for overload, wiring fault and protection working
- phone and coax protections, albeit with a different layout
- rotating cable entry point with 180° of freedom
At first glance, I find the old model more aesthetically pleasing. But the rounded design did cause some inconveniences over the years, such as power bricks not sitting down correctly due to uneven support. From a pure functionality viewpoint, the more industrial modern design is less likely to cause issues with that.
Now let's move on to what is different.
My Little Switches
Have you ever accidentally hit the switch on a power bar? It is The. Worst. Possible. Thing. And it has happened to me two or three times while using the old model with its large rocker switch recessed in that large cup. On the new model, the switch sits down in a slot that's barely finger-wide, making accidental toggling far less likely. Also, APC's newer model uses a combination breaker switch. The old model had its plain switch on top and a separate button-style breaker on the opposite side from the cable entry point.
The three LEDs arranged as an arc over the power switch on the old model look cute. But the nicely aligned lights on the new model look more organized and are much easier to interpret. Granted, you only need to read them once to know what each color means, so readability is not a major concern. However, improved organization does come out better overall in my opinion.
The red LED lets you know there is an issue with the outlet's electrical wiring, the yellow one tells you too much stuff is plugged in and the green one is your indication that the surge suppression is operational. If the green LED stops lighting up while the bar is on, it is your cue to cash in the lifetime replacement warranty.
Which childproofing method do you prefer? The new model's manual sliding shutters that you have to close any time you unplug a device, or the old one's interlocked spring-loaded shutters, which force you to simultaneously insert something into both blade slots to clear them? Personally, the amount of force it takes to push plugs through the spring-loaded mechanism bothered me quite a few times. But in terms of safety, it's the better protection of the two, since there's no real way to accidentally bypass it.
Another difference some of you may care about if you use your power bar's switch to turn accessories on or off is that all outlets on the new model are switched. The old model had three always-on transformer pad outlets for devices like broadband modems, routers, switches, telephony adapters, cordless phones and chargers. This is a trade-off related to the new model using a combination breaker switch instead of having separate devices for each function like the old bar.
The Black Labels
The new model's label has the same warnings in both French and English. Those of you who read my original picture story may remember how I poked a bit of fun at APC for providing different warnings. The “Patent Pending” mention is gone on the new label, and so is the CSA mark.
Surprisingly, the new unit has higher surge suppression voltage ratings than the old unit: 400V line-neutral and 500V for all other pairs versus the older unit's 330V everywhere. Given $300,000 equipment protection, I would have expected clamping thresholds to get tighter (closer to 120VAC or 170VPK) instead of wider to further reduce the amount of let-through. The only way to better understand APC's decisions is to get inside and look more closely at the hardware.
Six screws and a few nudges later, we're in.
The outlet area employs the same layout and strip styles, but is wired slightly differently since the old model had non-switched outlets. APC's new sample has the same daisy-chained grounds for phone and coax protection as my tear-down unit from two months ago, while my third older specimen utilizes a single circuit board handling both functions. I was not expecting that, but hoping for a surprise was the main reason I decided to use my last unopened unit for this story instead of reusing photos from the last one. Moreover, based on serial numbers, this one appears to be older.
In the previous two tear-downs, the outlet contact strips were either held down by melted plastic, plastic partitions they snapped into or were tangled in wires, making extraction inconvenient to the point that I didn't bother. In the new model, everything can be pulled out with relatively little effort. I decided to take a closer look this time around.
From left to right, the first two strips are different angles of the live and neutral connections behind the power brick pad outlets. The picture conveys the amount of “spring arm” between their wedge-shaped contact tips and the bus strip. The middle strip is the ground. The rightmost two are different angles of the strips used for the live and neutral connections behind the center row outlets; the middle contact has “wings” and the outer ribs to help guide plug blades in-between. As far as I can tell, all three strips are exactly the same as my decade-old SurgeArrest bars.
