Wacker, electromagnet heatsink bendy spring ping pop switch

[carlstanton]

All the years I've been installing these, I've never actually opened one up.that was quite interesting!

[dofrint]

RCBO, it's new for me . In Indonesia we simply call it MCB, Miniature Circuit Breaker .

[Marcel_Germann]

Most was already named. The resistor seen on 0:15 on the left upper corner is to limit the current on the bypass of the RCD coil which is used when you press the test-button.

[alexstone]

I find the whole assembly fascinating, the arc dissipator thingy is genius and the circuitry is made quite failproof overall without melting fuses


I guess the key components would be
- Bimetalic strip for slow overload protection, i think it's in RCBOs too?
- The coil for fast overload protection and short circuit protection
- The current transformer for current leakage detection with it's circuitry made with SCRs as the shorting component usually
- The arc disipator heatsink, to stop the arc as fast as possible

[nojukuramu]

can you try over loading it while we can see its components? i want to see how exactly it tripoff after short circuits or something

[eliadbu]

It's interesting that in English it's called RCBO. In my native language it is called after an acronym that stands for
"Automatic Switch Thermal Magnetic".

[ianicus]

If you took out everything but the switch, you'd have a Chinese breaker.

How to test 0.03A RCBO/ELCB is working to protect Human?

[syxalite]

Fun fact: it was invented in 1923 by Hugo Stotz in Deutschland, which is why in Deutschland and Switzerland they call it "stotz"

[toyotaWalsh]

Never took one w/Ark arrested apart before thanks

[Александр-яшж]

Да ты монстр!
Я тоже в 5 лет любил так делать, но т.к. дрель была тогда ручная и то не увсех, я делал это молотком.😄😄😄😄😄😄😄😄😄🤣🤣

[andreasu.]

Sure can do:
- Funkenlöschkammer
- Elektromagnetischer Auslöser
- Schlaganker
- Bimetallauslöser

[BGTheelectrician]

Arc Shute, magnetic trip, and bimetal for thermal trip.

The gizmo, the thing-a-majig, and the doohickey

[Justin]

Bro you didn’t even teach me what that was it’s just you pulling it apart

[AltharIV]

Single pole RCBO ? Where is the nuetral ?
The blue cable? This is new to me 🐱
