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; protection function, but it will be disconnected from the live wire at the same time, the width is 18mm; 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. |
