With the increasing popularity of plastic case circuit breaker, it involves various fields, even at home. The use of plastic case circuit breakers is even related to people's life safety. They can not be purchased and used at will, nor can they be thrown away directly after they are not like other commodities. Once the quality of plastic case circuit breaker is not up to standard, it will cause serious consequences.

So how should we choose plastic case circuit breaker?

Industry professionals advise consumers to buy machines with certification standards. For example, it has IEC logo and GB standard for low-voltage electrical appliances in China, and these are the most basic certification. With the increasing internationalization of domestic standards for low-voltage electrical appliances, only machines that meet this standard can be used.

I. Three Certifications of Machines - Standard Certification, Quality Certification and Safety Certification

In addition to standard certification, plastic case circuit breakers should also have quality certification, such as IS0 international quality system certification, classification society ISO quality system certification and so on. Why does the plastic case circuit breaker need the ISO quality system certification of classification society? Because this quality certification shows that the machine is reliable, and the performance of moisture-proof and vibration-proof is good, only through these two certifications, can the product be used normally. Certainly, security certification is also essential. Security certification is divided into sub-regions, such as UL certification in the United States and CCEE certification in the Great Wall. If you buy domestic plastic case circuit breakers, you must have the latter certification.

If you want to buy a qualified plastic case circuit breaker, you have to check whether it has the certification standards described above. If all certifications are available, the quality and safety performance are qualified.

2. After possessing three major certifications, it is necessary to select and purchase suitable plastic case circuit breakers according to the use environment.

If the rated current is below 630 A and the short circuit current is not very large, the plastic case circuit breaker can be selected. If the rated current is large, then it is better to choose a frame circuit breaker. If the short circuit current of the branch is large, other factors must be taken into account. However, one thing to note is that plastic case circuit breakers must have leakage protection measures, otherwise they can not be purchased.

3. Performance-price ratio of plastic case circuit breakers

After all the factors have been considered, it is necessary to consider the cost-effectiveness of plastic case circuit breakers. Different brands of plastic case circuit breakers have different prices and quality. Therefore, if consumers want to buy products with high cost performance ratio, they have to compare three products. Which plastic case circuit breaker is the most affordable and of the highest quality?

Expansion of Molded Case Circuit Breaker

The so-called extensibility is within a certain range, how about the load situation of the plastic case circuit breaker, and whether it can install module units to improve its functions.

To sum up: HKel think that when you buy plastic case circuit breakers, you must refer to the above criteria in order to achieve the purchase results of high value for money and cost performance. If you need help in choosing and purchasing, you are welcome to call the hotline 021-57161889.
