how the varistor protect the circuit from over voltage? in case if u had an over voltage, the varistor will burn but the voltage still be able to flow to the circuit
Two questions:- 1. Is it the aluminium wire that must be connected at both ends of a glass fuse? Actually, I connect both ends of a fuse with soldering wire, it connects with little trial and error. 2. I did the same with a 3 pin plug of Girish company with a 07d471k mov and 10ampere fuse.

Sir your video was so knowledgeable to me i understood what is actual use of MOV we need teacher like you 😊
My pleasure
Nice review,thanks but you should also inform in case there is short circuit after the fuse and about fuse rating etc.
Very good information for learner's or beginners,
Great work.
Parabéns pelo vídeo ótima técnica
Great idea, thanks a lot

Always use three-pin plug.
3 pin will be ideal for this kind of setup. You haven't tested it so you can't tell wheadef it's working or not
All appliances equipped with this spec MOV, sure it works, i don't have power line above 240V
If we only use fuse, will that not work properly?
High Voltage pass through fuse
apne varistor glat lgaya hai varistor ki dono legs plug k screw mein lgani hoti hai fuse se phelay nahi lagay gi..
Phir jab ye short hoga tu fuse kesy jaky ga, wiring kharab ho sakti hai, ya jab bhi lagta hai fuse je baad lagta hai
But, for example, a Led TV or a switching voltage source (for PC) do not have protections against voltage peaks?

We can use this circuit for ac 230 test lamp also
Lamp will burn on high voltag passing high volts spike to the load
You should connect thermistor after the fuse because when thermistor is gonna overload, fuse will blow.
How?
ruclips.net/video/_2GteAr7IpE/видео.html
@@ProGamer-pr9rw simply connect thermistor to the load side after the fuse.
That's what he did.

832👍
Good explaining👌
kitne voltage per fuse short ho jaiyega
Can we used mov on DC 12v ? And can it's protect 12v DC over current like 14v 15v etc
Yes, we can use varistor that has dc clamping volt 14V
Z👏👏👏👏
can i use variastor of 471,1kv plz reply
No
Can we connect varistor directly without fuse?
Yes, but fuse should be according to the load in DB
is it better to send the surge to neutral or ground wire
Neutral
how the varistor protect the circuit from over voltage? in case if u had an over voltage, the varistor will burn but the voltage still be able to flow to the circuit
If load consumption is 5A, we can use 10 or 20A varistor, when varistor shorts , 5A fuse easily burn that is before varistor
Cartridge fuse rating?
Very Helpful video thank you so much
So nice of you
Can i use any specification number of mov ?
No . According to the voltage
