What is IEC EN 60947-4-1?

IEC EN 60947-4-1 is a technical standard for low-voltage switchgear and controlgear. It specifies requirements for circuit-breakers, disconnectors, and fuse-switches that are intended to be used in distribution boards and switchgear assemblies.

This standard provides guidelines for the selection of electrical devices and equipment used in electrical installations. It covers aspects such as performance, functionality, and safety requirements ensuring their reliable operation and protection.

Key Features of IEC EN 60947-4-1

This standard has several key features that are important to understand:

1. Operational Safety: IEC EN 60947-4-1 sets forth safety criteria to ensure that the devices function correctly, minimizing the risk of electric shock or fire hazards.

2. Performance Requirements: It defines specific performance requirements for the devices, including fault conditions, resistance to mechanical stresses, and environmental influences.

3. Selectivity: The standard emphasizes selectivity, which refers to the ability of a device to isolate and disconnect only the faulty portion of an electrical installation while keeping the rest of the system operational.

The Importance of Complying with IEC EN 60947-4-1

Compliance with IEC EN 60947-4-1 is crucial for various reasons:

1. Safety: By adhering to this standard, manufacturers ensure that their products meet stringent safety requirements, reducing the risk of accidents and protecting both users and property.

2. Reliability: The standard's performance requirements guarantee the reliability and operational efficiency of devices, minimizing downtime, and ensuring uninterrupted power supply.

3. International Acceptance: IEC EN 60947-4-1 is an internationally recognized standard, making compliance essential for manufacturers who want to sell their products in global markets.

In Conclusion

IEC EN 60947-4-1 plays a critical role in ensuring that low-voltage switchgear and controlgear meet the necessary safety and performance requirements. By complying with this standard, manufacturers can provide reliable and safe electrical devices, contributing to the overall stability of electrical installations. Users can have confidence in products that adhere to IEC EN 60947-4-1, knowing that they have been tested and proven to meet international standards.
