Hey all!

Im kinda stucked here with these symbols. Does anyone have any idea?

1. I think its a terminal, but Im not that sure, since it is connected to a circuit-breaker (which is connected to a transformator)

2. Just to clarify, is 250A the current rating of the circuit breaker?

3. What does this "M" stand for?

4. What does this "C" stand for?

5. What does this "12 of" stand for?

6. "EG" ?

Thanks a lot for all the help!

 

Welcome

250A is the current capacity.

M stands for Manual cutoff I presume
C could be cut out

I can't say anything abt "12 of" without seeing the whole diagram

EG could be a an AC Motor

 

Thank you for the welcome <3

Umm heres the circuit breaker with "4 of" is just connected to a bus. The same thing with the "28 of"

And any idea with the symbol 1? ><

 

They could be contacts of the cutouts

 

The "4 of" 630A usually means that there are 4 630A breakers on that bus (and likely will show up on another diagram showing what they feed)

 

could be.......

 

it can also be 4of 28 means its current carrying capacity is 4%of 28A it can mean this also
