Title: What is BS EN 61434:2018 and BS EN 166:2020? A Comprehensive Guide

Electrical equipment is an essential part of our daily lives, and it is crucial to ensure its safety and reliability. One of the critical components of electrical equipment is circuit-breakers, which are designed to protect electrical circuits from overload, short-circuit, and other faults. However, designing, manufacturing, and using circuit-breakers effectively requires adherence to high safety and performance standards. In this article, we will explore the technical details of BS EN 61434:2018 and BS EN 166:2020, two important European standards that provide manufacturers, installers, and users with clear guidelines and requirements for designing, manufacturing, and using circuit-breakers that meet high safety and performance standards.

What is BS EN 60947-62?

BS EN 60947-62 is a technical standard developed by the International Electrotechnical Commission (IEC) to ensure the safety and performance of low-voltage switchgear and controlgear devices. This particular standard focuses on the requirements and tests for circuit-breakers. It aims to provide manufacturers, installers, and users with clear guidelines and requirements for designing, manufacturing, and using circuit-breakers that meet high safety and performance standards.

Key Requirements and Tests

BS EN 60947-62 provides manufacturers with requirements and tests for the design, manufacture, and testing of circuit-breakers. Key requirements and tests include:

Electrical Safety: The standard outlines the essential electrical safety requirements for circuit-breakers, including maximum allowable voltage (MAV), voltage rating, and insulation resistance.

Performance: The standard specifies the tests and procedures for measuring the performance and reliability of circuit-breakers, including short-circuit, overload, and thermal tests.

Safety: The standard provides requirements for the safety of workers and others who may come into contact with the circuit-breakers, including requirements for eye protection and electrical isolation.

Environmental Protection: The standard specifies the environmental conditions to which the circuit-breakers should be exposed, including temperature, humidity, and vibration.

Maintenance and Repairs: The standard outlines the maintenance and repair requirements for circuit-breakers, including the frequency and procedures for testing, cleaning, and repairing.

marking and documentation: The standard specifies the marking and documentation requirements for circuit-breakers, including the use of test symbols, markings, and documentation.

BS EN 166:2020

BS EN 166:2020 is a European standard that outlines the specifications and testing methods for personal eye protectors. It applies to all types of eye protectors used for general occupational applications, including those designed to provide protection against optical radiation, liquid droplets, mechanical hazards, and more.

The standard defines various parameters to ensure the quality and performance of eye protectors, including the field of vision, optical characteristics, resistance to ignition, robustness, compatibility with other PPE, and more. Manufacturers need to comply with these requirements to obtain certification for their eye protectors.

Conclusion

BS EN 61434:2018 and BS EN 166:2020 are two important European standards that provide manufacturers, installers, and users with clear guidelines and requirements for designing, manufacturing, and using circuit-breakers that meet high safety and performance standards. Adhering to these standards is essential to ensure the safety and reliability of electrical equipment, including circuit-breakers. By understanding the technical details of these standards, manufacturers can design, manufacture, and test circuit-breakers that meet the requirements of BS EN 61434:2018 and BS EN 166:2020, ensuring the safety and performance of electrical equipment.
