BS EN 60947-2:2018 is a technical standard that specifies the requirements and test methods for low-voltage switchgear and controlgear. It applies to circuit-breakers, switches, and similar devices designed for rated voltages up to 1,000 V AC or 1,500 V DC.
Scope of BS EN 60947-2:2018
The scope of this standard covers a wide range of products such as miniature circuit-breakers, molded-case circuit-breakers, and air circuit-breakers. It also includes control-circuit devices, switches, disconnectors, contactors, and motor-starters.
This standard sets the guidelines for their construction, performance, testing, and certification. It aims to ensure the safety, compatibility, and reliability of these devices across different applications.
Main Requirements of BS EN 60947-2:2018
One of the key requirements of this standard is the verification of the device's electrical endurance. It specifies the number of operations that the device should be able to withstand without any significant deterioration of its performance.
The standard also covers environmental conditions, mechanical requirements, and the capability of the device to withstand abnormal operating conditions such as short-circuits. It provides specific details on temperature rise limits, dielectric properties, insulation coordination, and clearances within the equipment.
Furthermore, BS EN 60947-2:2018 defines the requirements for user information, marking, and documentation that should accompany the device. This ensures that proper information regarding installation, operation, and maintenance is available to the users.
Benefits of Compliance with BS EN 60947-2:2018
Compliance with this standard offers several benefits. Firstly, it ensures the safety of personnel working with or in proximity to the equipment. By defining performance criteria and test methods, the standard guarantees that the devices meet minimum safety requirements.
Secondly, adherence to BS EN 60947-2:2018 enhances the compatibility and interoperability of switchgear and controlgear devices. It ensures that different components from various manufacturers can be seamlessly integrated within a system.
Lastly, compliance with this standard helps achieve reliability and durability in electrical installations. By outlining strict constructional and performance guidelines, the standard minimizes the risks of failures, malfunctions, and downtime.
BS EN 60947-2:2018 plays a crucial role in ensuring the safety, compatibility, and reliability of low-voltage switchgear and controlgear devices. Adhering to this standard not only provides protection to personnel but also enhances the overall performance and longevity of electrical installations.
