can anyone help me to solve this problem? Thank you!
Moreover, Where can I find the symbol's meanings?

 

M is a contactor What function name would you give it?
O/L is self explanatory safety component.
Rather a simple circuit.
There is a PDF by Group Schneider on electrical circuits, I do not have the copy on this PC, if you cannot find it, I can transfer it over.
We do not go into in depth answers for Homework, the policy is to advise rather than provide in depth answers.
