Although the arc chutes are not functional with the case opened for vision, but it would be interesting to see the trip action in slow motion video. Or if the case was built complete as a teaching aid and was built with a clear case. Then a slow motion video would give us a great view of the arc flash being extinguished/or lessened in the channels.
Hello, can anyone tell if it is completely safe to use these CNC brand circuit breakers? I'm going to remodel the electrical panel in my house and I wanted to use 1P+N, all from the same brand. Do you recommend CNC?
@@gohangaming2248not a short circuit. A short circuit utilizes a magnetic trip coil which attracts according to the strong field created by the fault. This is actually a overload, which bends the bimetal strip which triggers the trip coil. Due to the grey strip there being made of 2 different metals which have different thermal expansion rates, so when a overload of current is added, the strip will bend towards the side which has the least rate of expansion trigging the breaker. Short circuit devices must respond as quickly as possible. Overload protection devices are too slow(relatively) to respond to ground faults/short circuits and damage could easily occur before the fault is cleared.
That grey piece is a bimetal strip that bends with under load due to the 2 metals used having different thermal expansion rates. Soon as the metal strip distorts enough and makes contact, it trips the breaker. This is an example of overload, and a over current will have a magnetic trip coil which attracts the trip bar itself due to the strong magnetic field created by the fault current.
It's how some North American breakers work. Each manufacturer has its own unique characteristics(such as size or connection type) but they essentially use the same internal components. Other than say a magnetic only, HIC, solid state, or GFCI's, they essentially have the same internals. It's going to be either magnetic action, or a bimetallic strip being bent until it makes contact, and both activate a trip coil. I believe this is correct. I can't say 100% because I have no idea how US standards work. But it has all the same principles as a Canadian breaker.
@@muhamadzahirsgahrir3117yes, because it's a metal strip made of 2 different types of metal. And they have different expansion rates, so when current/heat is added the strip bends towards the side with the least amount of expansion. Overloads work this part of a breaker, whereas short circuits use electromagnetic force to attract totally separate parts of the breaker, but still ends up activating the same trip coil.

теперь можно снять короткое замыкание, чтобы сработал электромагнит,
можно от сварочника 😉
Thanks a lot ❤❤❤
Thanks🎉
thanks the same friend

Is there a bi metalic strip???
yes there is
Overload
Mot overload
It's shot circuit in slow motion

Not how us breakers work

Le titre est maladroit
how?
just watch the video
Becoz the steel is heating arc chute is detecting the heat . Heat make a steel bending
