I was skeptical about the performance as I had read mixed reviews here but since I have testing gadgets at home I was pretty sure that I will order a refund if my piece fails my test. It was heartening to see that this switch works as described by seller. My test bench1. 0 to 290 V Variac for variable ac voltage2. Mastech multimeter3. Uni T multimeterResults1. The switch has a default setting of 170 for low and 270 for high voltage. Current setting was not 40A but was at 63A.2. Voltage accuracy can't be verified as my two multimeters have a difference of around 10 volts but this switch was 3 volts less than mastech indications always.3. The setting up is exactly as described in the manual but I found the push buttons very hard to press. The set button as well as the up down button.4. Fitment on rail was easy and no size issues.5. Build quality is good. As we can see its a chinese product renamed by an indian seller. I took this from Amazon and not alixpress considering the warranty which the seller is offering.6. Few ppl have written that it was not cutting off the supply immediately. In my switch it was cutting off instantly in case of low voltage as well as high voltage. No delay at all.7. Reconnect default time is 30 seconds which I find a bit too much so I have reduced to 9 secs in my switch. This 9 seconds delay will always be there even if supply is interrupted and you will have to wait for this time delay always. Indians will feel bad for this time duration as the neighbor will have his/her lights on 😋8. Also the high voltage limit of 270 seems too high to me so I got it down to 250v. Depending upon the distance from your distribution transformer you can decide whats good for your household. I got my current setting down to 20A since my normal load is unlikely to exceed 12A. You can get it down to whatever you like but dont leave it at 63A as its too high.9. Overall a good product and does the work as described. I just hope that its longlasting.After 5 days of usage: Working fine however I thought of testing the overcurrent limit today. Brought down the current trigger from my adjusted value of 20A to 6A. As I increased the load the switch tripped off at 4.5 A. It kept on tripping everytime. Current overprotection is not very accurate. I increased my current setting to 15A thereafter. Atleast its tripping earlier and not later. ### ⭐⭐ It works too late as 5s is too much *by M***D on 10 July 2018* When the power is on and setted to 240v and if u rise volt till 280vlts it takes time of 5 secs it's too late to cut off till then everything electronic equipment s will be harmed timing is too late it works good but 25 s is too much ### ⭐⭐⭐⭐ long term review *by D***I on 27 December 2018* I purchased it the first time and the product was either defected or of inferior quality. so it lasted for only two weeks. But to my surprise, the seller contacted me after reading my previous review and sent me another product, which is seeming robust and of better quality. it was a good gesture from the seller and hope that they will continue this. another long term review will be followed after 3-4 month of usage.10/06/2019After usage of around 6 more months, I can say,that product is reliable and safe for sensitive and costly equipments. Having load of 4 ac and various appliances, this is running fine, which is contrary to my expectations 😀.Ordering another for my business. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/154061890-amicismart-automatic-over-under-voltage-adjustable-setting-protection-with-auto](https://www.desertcart.tn/products/154061890-amicismart-automatic-over-under-voltage-adjustable-setting-protection-with-auto) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-31*
