What is BS EN 60947-2:2018?

BS EN 60947-2:2018 is a technical standard that specifies the requirements for low-voltage switchgear and controlgear. It sets out the guidelines for the design, construction, and performance of electrical equipment used for controlling, protecting, and monitoring electrical power systems.

The Importance of BS EN 60947-2:2018

Compliance with BS EN 60947-2:2018 is crucial for ensuring electrical safety in various applications. This standard ensures that electrical equipment meets the necessary safety standards and provides reliable protection against electrical faults, thus minimizing the risk of accidents or fires.

With BS EN 60947-2:2018, both manufacturers and users can have confidence in the quality and safety of electrical switchgear and controlgear products. The standard covers a wide range of devices, including circuit breakers, disconnectors, and contactors, making it applicable to many industries.

Key Requirements of BS EN 60947-2:2018

The standard outlines several key requirements that electrical equipment must meet:

Temperature rise limits: Devices must be designed to ensure that they do not overheat during normal operation, which could lead to malfunctions or fire hazards. BS EN 60947-2:2018 specifies maximum allowed temperatures for different components and operating conditions.

Clearances and creepage distances: To prevent electrical arcing and leakage currents, minimum distances between conductive parts are specified. These distances ensure that insulation barriers are sufficient to withstand the electrical stress.

Protection against electric shock: The standard requires that switchgear and controlgear devices provide adequate protection to prevent accidental contact with live parts, reducing the risk of electric shock.

Short-circuit withstand capability: Electrical equipment must be able to withstand the high currents generated during short-circuits without suffering damage. BS EN 60947-2:2018 sets out the requirements for the mechanical and electrical strength of devices to ensure safe operation under fault conditions.

Conclusion

BS EN 60947-2:2018 plays a crucial role in ensuring the safety and reliability of low-voltage switchgear and controlgear. Compliance with this standard provides confidence that electrical equipment meets the necessary requirements for performance and safety. By following the guidelines outlined in BS EN 60947-2:2018, manufacturers can produce high-quality products, and users can select and operate electrical equipment with peace of mind, knowing that they are protected against electrical hazards.
