EuroControls EVP3PH - 3 Phase Voltage Protector - 63A - Adjustable Over/Under Voltage/Over Current/Voltage Asymmetry/Phase Sequence & Failure Protector - Auto Recovery Switch - Voltage & Amp Meter

Using it for 3 phase domastic supply. Working fine as of now priced little on higher side though.It has setting for both synchronous mode and asynch mode.Asynch mode means that if 1 or 2 phase power is gone the remainingvphase will continue to work. This is required for home 3P power supply as you are running different single phase loads on the three phases.Synchronous mode means that if voltange on one phase is low / high all three phase will be cut this is required for running 3phase load like a 3 phase motor.Just one thought if they can build RCCB functionality in same device it will be great as putting MCB , Voltage monitor /control , RCCB takes lot of space on DIN rail mount in DB box

Works fine... All 3 PH mode or indivual phase configuration. No problem for the past 5 months. Very easy to install & make the settings (I'm an Electrical Engineer).If you have voltage sensitive equipments like motor etc which would not run in wide voltage range of 180 V to 320 V... This is must for those who have 3 PH supply.

We have power fluctuations frequently and recently couple of items got burnt due to neutral disconnected somewhere in the transmission line, resulting in 415 volts. Got this one installed and is working fine now. It has got activated at least 5 times in one week, when the power went above or below the set value. The latch to hold the wires could be better designed. It is very shallow and smooth, so in effect it is unable to hold the wire tightly a small twist can pop the wires. Also the screws for tightening the wires could have been placed deeper, so that it prevents accidental touching. All in all it is working as expected as of now.

Purchased in Jun 2024. Product started malfunctioning in Apr 2025. They indicate a 1 year warranty but no contact information is available. I got their contact mail ids through Amazon support to initiate the communication for my warranty claim. But no response from these guys.

Very easy to install and the real time readings also give a good feel of the current and voltage drops caused by different loads.Since my home has 3 phase and neutral incoming, but all my loads are single phase, I have set it to asynchronous mode to protect against open neutral.The description in the Amazon site should mention that it is 5 modules wide.The system takes 5 seconds to restart every time there is a power outage, which means that there is an extra 5 seconds in the blackout duration in case of a power outage.Another small point to note. The smallest single phase current it can record reliably is 0.8A. The base current drawn by my appliances in standby mode is 140 VA, on one phase. This does not record at all. However, as soon as the current drawn comes close to 0.8 A, the current display flickers between 0 and 0.8A; at 0.8 A it holds steady, and then when the current drawn increases it then displays the value correctly.

Average product.

Replaced the 4 pole mains 40A MCB with this one as per electrician suggestion (as we don't have additional place in the panel). Better to check the manual before installing this to get yourself familiarized with settings. Factory settings worked for me, but had to increase the Over Voltage setting from factory defaults 250V to 270V as my line Voltage slightly exceeds or reaches 250V in few cases. The unit showed OV at that time and didn't allow the power to pass through. It properly displayed Voltage and current in each phase as shown in the picture.Have to see it's reliability.

The media could not be loaded. I was worried due to high voltage in my apartment, specially in midnight it goes 245v+.My Bosch washing machine power module burnt and for that I need to pay 10k.With this Eurocontrol voltage protector, I can sleep peacefully now.It cuts the phase supply at 245v (as configured by myself)Thank you Eurocontrol.
