What is the difference between these two?
What is the difference between these two?
(OP)
Hi all,
1) I was working on power distribution symbols and have seen these two symbol. What is the difference between two? Is there anyone that can explain?

and this one

2) Also are these ones electronic type cb symbol? Else how can I show that this cb is electronic type?
Thank you very much

Google "circuit diagram symbol" and select the standard you are working with. There is a very big difference between European and US symbols. The US NO relay contact is a European capacitor. As an example.

On the power side we show the IEEE numbers as the operators, and CT's if they exist. But here there may only be a small resistor to measure the voltage across.
This appears to have an electromechanical operator, rather than a pure mechanical operator.

Instead of showing transistor or Opamp, just mention SST,(Solid State Trip) and below LI (Long time and Instantaneous).
The shown symbol is from IEC world.
