Unit has not been put to the test due to no thunderstorms since acquisition and installation. Installation is simple as it is plug and play. I have a Clearline unit protecting my computer, printer and ADSL line which has been in service for more than 5 years. It survived a lightning strike which cooked my unprotected magnetic lock and its power supply. I purchased this as a precaution based on my experience with Clearline products. They are more expensive than other similar products but is worth it for the sake of practically proven efficacy and resultant peace of mind.

This unit works well, and does what it says on the box ... mostly. It also does a few things that it doesn't say on the box, some of which can catch you out. The technical specsheet for this product is poor, which is part of the problem.
As it turns out, the Tripconnect measures both the RMS (Root Mean Square) and the Peak value of the incoming mains in order to make a decision on whether the mains supply is "good". Think of the RMS and Peak values as "average" and "maximum" values respectively. It will disconnect the refrigerator if the mains goes above 260V (RMS), which is 13% above the nominal value of 230V (RMS). It will also disconnect the mains if the Peak value goes above about 368V. The specsheet doesn't give any of this information.
For normal mains voltage (ie from Eskom), this Peak-value checking doesn't cause any problem. But if you ever plan to use your fridge with a generator during an Eskom power outage, and you have a TripConnect, there's a possible problem. Most small generators (up to, say, 15kVA) don't have a very good quality output voltage (think of this as the "purity" of the output) and they tend to produce higher Peak voltages, even when the RMS is within limits. (For the technically-minded, this is because their output voltage is more triangular than sinusoidal). So when connected to a small generator, the TripConnect may deem the generator's supply voltage to be "bad" by virtue of its high peak voltage, even though the RMS value is actually fine.
The nett result is that your fridge may never switch on when used via a TripConnect with some generators. You can of course disconnect the TripConnect when used with a generator, but this kinda defeats the object.
It's not really the TripConnect's fault, but it is an issue Clearline might want to consider in a future revision. It would also be good practice of the specsheet told you about this.
So, in summary : fine for mains use, be wary if you plan to use it with a generator.
