What is EN 60947-5-2:2015?

EN60947-5-2:2015, also known as IEC 60947-5-2:2005, is an international standard that outlines the requirements for high-voltage switchgear and control gear. It specifies the design, construction, and performance of electrical equipment used in industrial and commercial applications.

The Scope of EN60947-5-2:2015

This standard applies to disconnectors, switches, circuit-breakers, and other similar devices that are designed specifically for controlling and protecting electrical circuits with a rated voltage above 1kV but not exceeding 52kV AC or 75kV DC. It sets forth the conditions for their safe operation, including various performance aspects and environmental conditions.

Key Requirements and Features

EN60947-5-2:2015 lays down specific guidelines for the design and testing of electrical equipment. Some of the key requirements include:

Operation under normal conditions: The equipment must be capable of proper functioning under normal operating conditions.

Clear indication and labeling: All relevant information, such as rating, switching position, and short-circuit withstand capabilities, should be clearly indicated on the equipment.

Predictable behavior during faults: The equipment should be designed and tested to ensure predictable and reliable behavior during fault conditions, such as short-circuits.

Electrical and mechanical endurance: The equipment must be able to withstand a specified number of operating cycles without any loss of life or deterioration of characteristics.

Protection against electric shock: Adequate protection measures must be in place to prevent electric shock or any hazardous contact with live parts.

Resistance to environmental conditions: The equipment must be designed to withstand a range of environmental conditions, such as humidity, temperature, and pollution.

Importance of EN60947-5-2:2015 Compliance

Complying with EN60947-5-2:2015 ensures that the electrical equipment used in industrial settings meets high safety standards. By adhering to this standard, manufacturers can guarantee that their products are reliable, durable, and safe for use in various applications. Compliance also helps protect personnel working with or around the equipment, minimizing the risk of electrocution, fires, or other accidents.

In addition, complying with international standards like EN60947-5-2:2015 enhances interoperability, allowing different electrical components from various manufacturers to work together seamlessly. This promotes flexibility and compatibility, facilitating easier installation, maintenance, and future upgrades.

Overall, EN60947-5-2:2015 plays a crucial role in ensuring the proper design, construction, and performance of high-voltage switchgear and control gear. Its compliance ensures electrical safety, protects personnel, and contributes to the smooth operation of industrial and commercial systems.
