{839} Why MOV Varistor is Not before Fuse

{839} Why MOV metal oxide Varistor or vdr voltage dependent resistor, voltage arrester or tvs transient voltage suppressor (either unidirectional tvs or bidirectional tvs, class x or x-rated safety capacitor or class y capacitor is Not before Fuse, why mov varistor protection is connected after fuse.
because fuse is a "short circuit current" protection and it is connected in entrance the supply voltage. due to any abnormal spikes of voltage or frequency will make internal short circuit to the mov / tvs / transil / thyrector, which will cause to produce a short circuit link across the line input voltage terminals. in result the input fuse will blow away from the unwanted voltage strikes, so the circuit will become protected. in case high frequency spikes the x-rated capacitor will provide our desired short circuit link across the line input voltage terminals. in result the input fuse will blow away from the unwanted high frequency strikes, so the circuit will become safe.

[@mhnoni]

Thank you, finally, now I understand what Varistor does. so it short the circuit on high voltage to let the fuse burn and cut the power.

I connected a varistor accross L & N, initially it worked but when i came back after a few minutes the appliance was not working. Turns out there was 220v in both L & N which got solved after removing the vatistor. What could have happened?

[@shahbaazahmad130]

Sir can u plz tell why electrolytic capacitor connected in output of SMPS got damage due to heating.

[@HaseebElectronics]

please check the output rectifier, and its snubber RC. or might be capacitor value is low value than the required capacitance, which may cause increase temperature due to more ripple current

[@FinlabVenture]

sir agar mcb laga hua ho toh fuse lagane ki jarurat hai ya nenhi sirf mov use kar sakte hai

[@HaseebElectronics]

Fuse jaruri hota he Mov over voltage ko detect karta he aur fuse over current se circuit ko protect karta he

[@shefqetkaralliu6816]

🙏Grazie 👍

[@HaseebElectronics]

it is my pleasure

[@deesevenengalan3678]

Nice very informative wenreally appreciate🙏♥️

[@Dennis-uc2gm]

Completely logical to put the fuse first otherwise it would become dangerous and could create a fire since the only protection at this point would be the breaker in the mains panel.👍

[@techchanneliq1634]

Sir I really appreciate your videos. They are very helpful. Can you please do a video on how to test inverter ac pcb components while still attach to the pcb. Example. Class X & Y capacitor, MOV, PTC and so on.

[@jboy4real]

How do select the right value of mov for either AC or DC source

[@ohmware2020]

most of the power supply, the fuse is connected in series with the live, while the ntc/ptc is in series with the nuetral

Sir , does an MOV have plus (phase) or minus (neutral) terminals . Can we connect either of the terminals to either phase or neutral.

[@HaseebElectronics]

MOVs provide bidirectional clamping, they are not a polarized device. we can connect it in any direction
