Brilliant clarity. Great effort that paid off big time. Michael

[@TechTricks786]

Well done 👍

[@Sienna.N234]

Awesome, clear diagrams mate good job! I subscribed :)

[@AboutElectricity]

Cheers mate!

[@pieterkruger4134]

please demonstrate wiring the lovato pmv95 n with 2 contactors in series. one contactor to disconnect the main circuit if there is voltage issues and the other contactor to disconnect the main circuit in case of frequency issues

[@ytenginer5835]

Great installasion👍

Sir Want to install phase sequence relay for 5 hp 3 phase motor.. Is motor HP is to be considered before buying. Phase failure relay.....

[@ignacioxxi]

Great videos! Thanks for sharing

[@AboutElectricity]

Thanks, I am glad to hear it.

[@paulmc7853]

How does the led light up if all 3 phases are lost? Is the contactor coil energised all the time and when the supply is lost it opens? Cheers

[@jimmyordiz9505]

this is great

[@tabasumcarpentry5336]

Great video . One question is it necessary to add fuses above the relay thank u

[@supermick83]

ABID Abid Yes as these protect the much smaller control wiring. Otherwise if a fault occurs the control wiring will most likely melt and cause all sorts of issues including at worst a 🔥. Hope this helps

[@tabasumcarpentry5336]

Sir thinking to install a contactor with phase faller relay as a power source to machines in case of phase loss the machine power off. currently its connected thorough 3 pole MCB three machines each on 30 amps MCB will it ok to do this for all 3 machine means each machine has separate contactor with phase failure relay or install a large 80 amps contactor with a phase failure relay to feed all three mcb kindly guide on this thank u

[@tabasumcarpentry5336]

instead of fuses can we use 10 amp breaker? thank u if necessary

[@AboutElectricity]

Yes, you can.

[@jeromeacacio2876]

is it necessary to use a 3Ph 4Wire(with neutral) Phase monitoring relay for a voltage system with neutral or a 3Phase 3Wire model is good enough?

[@AboutElectricity]

it all depends on whether the voltage sensing relay has a neutral terminal or not.

[@jimmyordiz9505]

i have a question if the system experience single phasing...is the phase monitoring relay will trip to off?and to function again is to reset the phase control relay?ty

[@AboutElectricity]

If you have all 3 phases then 11 - 14 contact will be closed. If you got only one phase the relay will open contact 11-14 deenergizing the contactor. When power supply have 3 phases again the contact 11-14 will close again and you will need to press START to energize the contactor.

Sir can we control 2 80 amps contactor with one phase failure relay through terminal loop. I have the same schinder relay as in above video Thank u

[@AboutElectricity]

I can't see the reason why not.

Hi everyone !

[@ak18101]

Avoid music and explain

[@omedelind1139]

Where is the motor overload protection? T

[@AboutElectricity]

Above contactor.It is motor protection switch.
