Moulded case circuit breakers also have short-circuit protection and overload protection, while for the protection of personal safety and the safe operation of electrical equipment. Circuit breakers are widely used and therefore there are many types of circuit breakers.

What should I look for when buying a moulded case circuit breaker?

Three major certifications for machines - standard certification, quality certification and safety certification

With standards to carry out certification work in addition, plastic-case circuit breakers should also have quality management certification, such as IS0 international environmental quality control system certification, classification society ISO quality evaluation system certification technology and so on. Why do we need to have the classification society ISO quality analysis system certification for plastic-case circuit breakers? Because for this information quality certification shows that this machine is very reliable, and moisture and vibration resistance are good, only students through the study of these two certifications, to show that the enterprise products can affect the normal life use. Of course, the issue of safety education certification is also essential, safety certification sub-regional development of the division, such as the United States UL certification, the Great Wall CCEE certification, if not everyone buying a domestic plastic case circuit breaker, must have the latter this professional certification.

If you want to buy a quality-qualified plastic case circuit breaker, you must check it for the above certification standards. If all certifications are available, the quality and safety performance is acceptable.

There are 3 main certifications that are also required to use the environment to select and purchase the appropriate plastic case circuit breaker

If the rated current is below 630A and the short circuit current is not very high, you can choose a plastic case circuit breaker. If the rated current is higher, a frame type circuit breaker is preferable. If the branch circuit has a very high short-circuit current, other factors must be considered. It should be noted, however, that the moulded case circuit breaker must have leakage protection, otherwise it cannot be purchased.

Cost-effectiveness of moulded-case circuit breakers

Having considered all factors, it is necessary to consider the cost effectiveness of moulded case circuit breakers. Different brands of moulded case circuit breakers are available at different prices and quality. So consumers have to shop around to find out which plastic case breakers are affordable and of high quality if they want to get a cost-effective product.

Extensibility of plastic-case circuit breakers

The so-called extensibility is to carry out a certain range of how the load development of the plastic case circuit breaker, can install a modular design unit to enhance the function of the enterprise itself.
