Dongguan 2016 Chashan Electrical Circuit Breaker teaches you how to use it for training

According to the text symbols and graphic symbols in the circuit, a one-to-one correspondence between these simple symbolic information and the actual physical parts and components is established to further clarify the meaning expressed in the circuit and to understand the circuit relationship. Very important. Figure<>-shows the symbols in the simple electrician circuit mentioned above
