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

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

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

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

[tabasumcarpentry]

Great video .


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

[tabasumcarpentry]

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

[jeromeacacio]

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?

[jimmyordiz]

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

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

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

Where is the motor overload protection?
