Title: What is BS EN 60669-1 and BS EN 60898-2? 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 two key standards that are relevant to circuit-breakers: BS EN 60669-1 and BS EN 60898-2.

What is BS EN 60669-1?

BS EN 60669-1 is a technical standard published by the International Electrotechnical Commission (IEC) that specifies the requirements for low-voltage switchgear and controlgear devices. This particular standard focuses on the requirements and tests for circuit-breakers. The standard aims to ensure the safe operation and performance of circuit-breakers, while maintaining their electrical and thermal properties.

The standard provides manufacturers, installers, and users with clear guidelines and requirements for designing, manufacturing, and using circuit-breakers that meet high safety and performance standards. It covers various aspects, including the mechanical, electrical, and thermal requirements for circuit-breakers, as well as the testing procedures that need to be followed.

What is BS EN 60898-2?

BS EN 60898-2 is a technical standard developed by the IEC to ensure the safety and performance of circuit-breakers for overcurrent protection. The standard pertains to circuit-breakers that are intended to protect electrical installations against overloads and short circuits.

The primary purpose of BS EN 60898-2 is to provide a standardized framework for the design, construction, and testing of these circuit-breakers. It covers both manufacturer responsibilities in producing compliant circuit-breakers and user responsibilities in selecting and using them correctly. The standard takes into account factors such as rated operational voltage, rated current, breaking capacity, coordination with other protective devices, and environmental criteria.

BS EN 60898-2 is an essential standard for anyone involved in the design, construction, and testing of circuit-breakers. By adhering to the requirements and testing procedures outlined in the standard, manufacturers can ensure that their circuit-breakers are safe, reliable, and meet the necessary performance standards.

Conclusion:

BS EN 60669-1 and BS EN 60898-2 are two critical standards that are relevant to circuit-breakers. These standards provide manufacturers, installers, and users with clear guidelines and requirements for designing, manufacturing, and using circuit-breakers that meet high safety and performance standards. By following the guidelines and requirements outlined in these standards, electrical equipment can be designed, installed, and operated safely and reliably.
