What is BS EN 606173:2011?

BS EN 606173:2011 is a technical standard that specifies requirements for the safety and performance of electrical equipment in low voltage distribution systems. This standard was developed by the British Standards Institution (BSI) in collaboration with industry experts to ensure the safe operation of electrical installations in various environments such as residential, commercial, and industrial buildings.

Scope and Application

This standard applies to electrical equipment used in low voltage installations where the voltage does not exceed 1000 volts AC and 1500 volts DC. It covers a wide range of equipment including switchgear, control gear, fuses, circuit breakers, and transformers. These devices are crucial components in the distribution system and must comply with stringent safety and performance requirements to minimize risks of fire, electric shock, and other hazards.

Key Requirements

BS EN 606173:2011 sets out several key requirements that electrical equipment must meet to ensure safety and reliability. Firstly, it specifies the constructional requirements, including insulation materials, mechanical strength, and protection against environmental factors such as humidity and temperature variations. Secondly, it defines the requirements for electrical characteristics such as rated voltage, current-carrying capacity, short-circuit withstand capability, and fault protection. Additionally, it addresses aspects related to documentation, marking, and instructions for installation, operation, and maintenance.

Certification and Compliance

Manufacturers and suppliers of electrical equipment need to undergo a thorough testing and certification process to ensure compliance with BS EN 606173:2011. The certification process typically involves independent testing by accredited laboratories to verify that the equipment meets all the necessary requirements. Once certified, the equipment can be marked with the appropriate conformity symbols, indicating that it conforms to the relevant safety standards. Compliance with this standard not only provides reassurance to users but also ensures regulatory compliance and facilitates international trade of electrical equipment.
