1. What is a miniature circuit breaker?
It can connect, carry and break the current under normal circuit conditions. Under specified abnormal conditions (such as short-circuit current), A mechanical switching device that can also switch on, carry-fixed time and break current.
With current overload protection and line short circuit protection, the rated current does not exceed 125A 
2. How to choose the right circuit breaker?
The circuit breaker is generally selected at 1.5 times the normal working current.
3. What is the difference between 2P and 1P+N of circuit breaker?

Prepresents the number of poles, N represents the zero line, 2P represents that both poles of the miniature circuit

breaker have thermal and magnetic protection functions, and the width is 36mm;
And 1P+N, only the hot wire thermal magnetic protection function, the N pole has no thermal magnetic

protection function, but it will be disconnected from the live wire at the same time, the width is 18mm;
Therefore, 1P+N is more economical than 2P, and it also has higher safety.

It is suitable for applications with small current such as lighting circuits.
4. How to get a quote?
Please contact our sales staff and leave a message that you need which poles, current, quantity, EXW/FOB or CIF, 
we will reply you as soon as we receive the message.
