With the moulded case circuit breaker MCCB more and more popular, many industries can be used, the family can also be used. But molded case circuit breaker is close to personal safety, can not casually buy. It is not like ordinary goods, buy do not like to throw away directly. If the quality of moulded case circuit breaker, however, will cause very serious consequences. So what kind of Molded Case Circuit Breaker Should I buy? The industry believes that consumers should buy a machine with certification standards. Such as the IEC logo and China's low-voltage electrical appliances GB standards, these are the most basic. At present, China's low-voltage electrical standards more and more international, all meet the standards of the machine can be used.
With the standard certification, the moulded case circuit breaker mccb should also have quality certification, such as IS0 international quality system certification, classification societies ISO quality system certification and so on. Perhaps we will be very curious, molded case circuit breaker why have this quality certification behind it? Because this quality certification that this machine is very reliable, and moisture and anti-vibration performance are good, only through these two certification, only that the product can be used normally. Of course, safety certification is essential, where the safety certification is a regional division, such as the United States UL certification, the Great Wall CCEE certification, if you buy the domestic Molded Case circuit breaker, there must be behind this certification.
To get the quality of the moulded case circuit breaker mccb, you have to check it has not introduced above the certification standards. If all certifications are available, the quality and safety performance is acceptable. Next, consumers need to choose according to the specific use of the environment. If the rated current is below 630A, the short circuit current is not very large and you can choose the molded case to make the circuit breaker. If the rated current is large, then the best choice of frame-type circuit breakers. If the branch short-circuit current is very large, you have to consider other factors. But one thing to note, that is, molded case circuit breaker must have leakage protection measures, or can not buy.
After all the factors are considered, you have to consider the cost of molded case circuit breakers. Different brands of molded case circuit breakers, the price is not the same. All consumers want to buy more cost-effective products, it would have to shop better than three, to see which of the Molded Case circuit breaker price the most affordable, the highest quality. After these basic requirements are met, you have to consider the expansion of molded case circuit breakers.
The so-called scalability is within a certain range, Molded Case circuit breaker load situation how, can not install the module unit to enhance their own function. These things are really very important, please be sure to consider clearly.
