FAQS

答： R、S、T是变频器三相电源的输入端子。U、V、W是变频器的输出端子，而连接的三相异步电动机P+和PB则与制动单元相连，P+和P-则与直流电源(太阳能电池板)相连。

答：我们的生产严格遵循ISO9001质量控制体系。经过四次质量检查和高温测试后，我们会印上“QA”通过标识。

答:我们接受在您的授权下进行OEM和ODM。

答：我们提供从1A到125A的直流微型断路器，以及从63A到630A的直流塑壳断路器。

答：我们的直流微型断路器是为太阳能光伏系统设计的，直流微型断路器中的所有部件都符合直流标准。并不是所有的微型断路器都是直流微型断路器!

答：在正常电路条件下，它能够连接、承载和分断电流。在特定的异常条件下(如短路电流)它还能作为一个机械开关装置，实现接通、承载固定时间以及分断电流的功能。
具有过载保护和线路短路保护，额定电流不超过125安培。

A:We can make 300,000 pole one month. If you have order plan, feel free to contact us, I will tell you delivery time according to your demand.

A:The circuit breaker is generally selected at 1.5 times the normal working current.

A:P represents 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.

A: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.
