Many equipment in the process of use will occur failure, then high and low voltage distribution box in use will also appear the corresponding failure, such as high and low voltage distribution box switch trip fault, then the distribution box main fault causes what? Xiaobian below to the main analysis.

In the front, it is likely to be related to the quality of the high and low voltage distribution box, the user may not pay attention to the quality of the purchase of distribution box, and now on the market some unqualified distribution box also exists, therefore, the quality factor is also the main reason for the failure of the distribution box, may be some models of improper use of contactor led to its brake burned out, This caused the failure.

Second, the fault cause of the high and low voltage distribution box is also linked to the surrounding temperature factors, such as some high temperature, low temperature and humid environment will affect its use, and some distribution boxes are set outside, but also affected by the high temperature of the sun, these high temperature factors can make the equipment temperature of the distribution box, making the high and low pressure distribution box components can not bear. As a result, some components in the electrical apparatus overheat phenomenon leads to the occurrence of failure.

Third, the fault of the high and low voltage distribution box is also related to the AC contactor in it. The model and specification are incorrect. For different lines of the distribution box, the capacity of the AC contactor is also different.

In a word, the above are the main reasons for the failure of high and low voltage distribution box, then there are other failures and reasons, in fact, for high and low voltage distribution box, the usual maintenance and maintenance is also very important, therefore, users should pay attention to the usual maintenance treatment.
