What is IEC EN 60947 4 1 ?

IEC EN 60947-4-1 is an essential standard for ensuring the safety and reliability of low-voltage electrical installations. Compliance with this standard is mandatory for manufacturers of distribution boards and switchgear assemblies.

The standard specifies the performance, functionality, and safety requirements for circuit-breakers, disconnectors, and fuse-switches used in distribution boards and switchgear assemblies. It provides guidelines for the selection of electrical devices and equipment, as well as testing procedures to ensure their reliable operation and protection.

IEC EN 60947-4-1 is an international standard that is widely recognized and accepted worldwide. It is important to note that this standard is only applicable for low-voltage electrical installations, and not for high-voltage systems.

Compliance with IEC EN 60947-4-1

Manufacturers of distribution boards and switchgear assemblies must comply with the requirements and testing procedures specified in IEC EN 60947-4-This includes ensuring that the products meet the relevant performance, safety, and environmental standards.

To ensure compliance with IEC EN 60947-4-1, manufacturers must conduct testing on their products to verify that they meet the relevant requirements. Testing typically includes environmental testing, thermal testing, and electrical testing, among others.

Benefits of Compliance with IEC EN 60947-4-1

Compliance with IEC EN 60947-4-1 is important for several reasons. First, it ensures the safety of the electrical installations, as specified in the standard. Second, it ensures the reliability and performance of the electrical devices, as well as their ability to operate within the specified environmental conditions.

Third, it provides manufacturers with a standardized testing procedure for their products, making it easier to ensure compliance with the standard. Finally, it helps manufacturers to reduce their risk of product liability in case of a product failure or incident.

Conclusion

IEC EN 60947-4-1 is an essential standard for ensuring the safety and reliability of low-voltage electrical installations. Compliance with this standard is mandatory for manufacturers of distribution boards and switchgear assemblies, and failure to comply with the requirements can result in significant consequences.
