Overload Relays (Full Lecture)

In this lesson we'll take a brief look at overload relays, a sensory device that protects a motor from sustained excess current draw. An overload relay will allow a harmless temporary overload such as an inrush condition during motor starting, however, will trip if current is high enough to cause motor damage over time. The overload relay can be reset once conditions causing the overload event have been detected and resolved. (Full Lecture)

Thank you Jim for making these great videos. I (we) appreciate your time Sir.

[@javierferrer4634]

Very nice video! I'm a dragline operator and a lot of this items are on it.

[@danp8126]

Good job on making basic information easy to follow and understand.

[@michaelcostello6991]

Great video. Thanks Michael

[@henrybartlett1986]

Informative as ever. Many thanks.

[@madhushamal92]

Very informative. Thanks a lot for your effort taken

[@chrisampere]

Nice explanation sir jim. Thanks.

[@user-lx6td6ri2c]

Thank you, sir.

[@k50159]

Thanks so much

Before I started studying this stuff, I never would have guessed that switches made of massive hunks of metal and plastic (and Rube Goldberg type devices involving melting metals) were part of the modern industrial scene.

MCB has bi-metal thermal tripping for continuous ( non- short circuit) over current, so how is it any different than overload relay?

[@Aadhvika_Vibes_04]

Hi Jim, Thermal overload is clearly explained. Please could you provide your inpur or make video like, With help of name plate information how can we can calculate the Trip class and Trip level (Sec) ? could you clarify this doubt

[@mariafreedom6069]

Interesting

[@anonymousperson2578]

Hello Jim, thanks for all the informative videos!

[@StoneysWorkshop]

If a pump motor claims to be thermally protected in single phase :automatic reset ,is it also necessary to have a motor starter setup on the power input?

[@foxxmulder7524]

HI JIM,

[@rodstalwart8338]

Why is all motor overload relays made in 3 phase? Is there one made for single phase motors? Or common 3 phase OR can be used in 2 phase motors too?

[@Dr-Shlomo-Cohen]

My Samsung inverter makes circuit breaker of the house go off as soon as the compressor starts. Lately the compressor has been making noise. No short between windings and the ground 11.7ohms between each winding. Do you have any suggestions?

[@nataala_]

Thank you for a great video.

I love the starting music 😀😁
