Air circuit breakers are important equipment in electrical systems, playing a role in protecting equipment and ensuring safe power distribution. To avoid potential equipment damage and danger in the event of overload or short circuit. Therefore, when choosing an air circuit breaker, it is necessary to understand its certification standards. The common certification standards are IEC and UL, ensuring that circuit breakers meet strict safety, reliability, and performance standards. Only products that have passed these certifications can ensure their effectiveness and safety during use.
What is IEC certification?
IEC is a global organization responsible for developing international standards for electrical, electronic, and related technologies. IEC was established in 1906 to provide standards that ensure the safety, performance, and environmental compatibility of electrical products. For air circuit breakers, IEC standards play a crucial role in ensuring safe operation of equipment in high voltage environments such as high voltage and electrical faults.
IEC standard for air circuit breakers
- The IEC 60947 series is the core standard for low-voltage electrical equipment, with IEC 60947-2 specifically addressing the performance and safety requirements for low-voltage circuit breakers, covering equipment below 1000V AC and 1500V DC
What is UL certification?
UL is an independent world safety certification firm founded in the United States. It specializes in providing product testing, inspection, and certification services for systems, materials, and products. UL certification defines that the product has been passed by the United States’ safety requirements and can be used without any danger. In the instance of air circuit breakers, UL ensures that they are in accordance with regional safety standards and can be easily used in the United States and other related markets.
UL standard for air circuit breakers
- UL 489 is a key standard for air circuit breakers in the United States. It specifies safety and performance requirements, including testing requirements for disconnection capability, electrical insulation strength, temperature rise, etc. By complying with UL 489 standards, manufacturers can ensure that their products comply with strict safety regulations in the United States and are suitable for industrial and commercial use.
Compare the main differences between IEC and UL certification
- Compliance with international and local standards
The biggest difference between IEC and UL certification lies in their scope of application. IEC certification is global, ensuring compliance with international standards; And UL certification is mainly applicable to the United States and its related markets. For manufacturers, obtaining these two certifications may be necessary to enter the global market.
- Testing and inspection procedure
Although the two certifications employ similar testing categories, the procedures themselves vary. IEC tends to cover broader international standards of safety, while UL focuses on adherence to specific safety regulations in America. These disparities might mean disparities in testing methods, equipment required, and inspection procedures.
- Benefits for manufacturers and consumers
For manufacturers, having IEC and UL certifications can not only expand market share, but also enhance brand reputation and ensure compliance with safety standards in different regions. Consumers can obtain more protection, ensuring that the purchased air circuit breakers undergo strict safety testing and have reliable performance.
Why do manufacturers need to obtain IEC and UL certifications?
For manufacturers, both of these certifications can enable products to access the global market, enhance global competitiveness, and gain consumer and business user acceptability in all corners of the globe. And IEC and UL certification ensures that air circuit breakers have undergone strict testing, including durability, performance, and safety. Aside from enhancing product quality, this can reduce the risk of equipment malfunction and build greater consumer confidence.
After the product has undergone relevant testing and certification, fees need to be paid and there are requirements for product quality. For some small businesses, this is often difficult to achieve. If you still want to enter the national market for trading, I suggest you apply for IEC certification. As long as you avoid the product entering the United States and its related markets, there will be no problem
