Mini Circuit Breaker Remote Tripping

Also please tell me how these auxillary parts will be coupled to MCB or RCD? anything like handle ties?

the contacts are mechanically connected .....if u ve seen mcb, sd,of ,mn or mx contacts then u wouldnt have asked this......the remote tripping is done with mx or mn coils...mn is a undervoltage coil which will trip the mcb when voltage drops below (0.7 supply voltage). and mx is a shunt trip coil which will trip the mcb once it s energised through a power supply..........remote tripping is done through a NO or NC switch linked to mx or mn coils........

Now I see apart from MCB many auxillary parts and what I cant understand is how say a shunt trip will trip the MCB?

It is mounted next to MCB and you sent the signal to the shunt trip ok? So this shunt trip coil will generate a mechanical movement true? so how this part will effect the position of a mcb? I ask this in fact.

Every page on the net as you tell the way how a shunt trip coil will operate but dont show how it will make a MCB operate.

Please tell me how they are linkaged...

when the shunt coil receives a signal , it will get energised and the contacts in it will move from its original position. these contacts are mechanically linked to contacts of mcb (if u visit a switchgear or panel manufacturing industry u will know in detail.)....so wen the contacts move (trip) in the shunt coil they will inturn trip mcb.....i cant explain more than this....u ll ve see them to know them

I think u speak of big circuit breaker. For them speaking I know how these coil are linked to mechanism of CİRCUİT BREAKER

I am asking of MCB s and as u can see from the file they are mounted next to each other and I cant see how can these contacts are linked...

Shamith,

No need to be rude, you can just resign from answering, you are not obliged, we are all here posting in a good will to help each other.

JINXNAO,

for the original question, on the left side of the MCb there is a hole, when you add a shunt trip, a pin from the shunt trip enter into this hole, and when energized this pin hit the mechanism of the breaker making it to trip,

I hope my answer was helpful. SAMITH gave you the right answer also but has not enough patience to follow it.

dear noble, I think I have much more ability of understanding than the guy u mentioned I have no doubt in that.

What u told me was very clear and nice opposed to what that guy told:)

İt is very easy to say the mechanisms are linked, but as you have proved it is easier than this to explain the essence of the fact. Thank you for your explanation. I thnik some guys need to have read the questions and what they ask then they can be helpful for us....
