What is BS EN 608251 ?

Title: What is BS EN 608251 and BS EN 60947-62? A Comprehensive Guide

Electrical equipment is an essential part of our daily lives, and it is crucial to ensure its safety and performance. The international standardization process helps achieve this goal by establishing common standards and guidelines for electrical equipment design, manufacturing, and testing. In this article, we will discuss two such standards: BS EN 608251 and BS EN 60947-6We will explore the purpose of these standards, key requirements and tests, and their significance in ensuring electrical equipment safety.

Purpose of BS EN 608251 and BS EN 60947-62

BS EN 608251 and BS EN 60947-62 are two technical standards developed by the International Electrotechnical Commission (IEC) to ensure the safety and performance of electrical equipment. While both standards address safety aspects, they have distinct differences in their scope and requirements.

BS EN 608251 is a technical standard that specifies the requirements for low-voltage switchgear and controlgear devices. It is divided into four parts, which cover the design, manufacture, testing, and documentation of these devices. The standard aims to ensure that manufacturers produce electrical equipment that meets the essential safety requirements and performs as expected.

BS EN 60947-62, on the other hand, is a more specific standard that focuses on the requirements and tests for circuit-breakers. It is part of a series of standards developed by the IEC to ensure the safety and performance of electrical equipment. The standard specifies the design, manufacture, testing, and documentation of circuit-breakers, with a particular emphasis on their safety features.

Key Requirements and Tests

BS EN 608251 and BS EN 60947-62 both have key requirements and tests that manufacturers must comply with to ensure the safety and performance of their electrical equipment. While both standards have similar requirements, they differ in their scope and depth.

BS EN 608251 primarily focuses on the overall design, manufacture, and testing of low-voltage switchgear and controlgear devices. It sets out the requirements for the electrical, mechanical, and thermal aspects of these devices. The standard specifies tests for various aspects of the device, including electrical continuity, insulation resistance, and voltage drop.

BS EN 60947-62, on the other hand, is a more specific standard that focuses on the requirements and tests for circuit-breakers. It sets out the requirements for the design, manufacture, testing, and documentation of circuit-breakers, with a particular emphasis on their safety features. The standard specifies tests for various aspects of the circuit-breaker, including breaking capacity, leakage current, and short-circuit protection.

Conclusion

BS EN 608251 and BS EN 60947-62 are both important international standards that help ensure the safety and performance of electrical equipment. While both standards have similar requirements, they differ in their scope and depth. The purpose of BS EN 608251 is to ensure the safe operation and performance of circuit-breakers, while BS EN 60947-62 is focused on the requirements and tests for circuit-breakers. By adhering to these standards, manufacturers, installers, and users can ensure that their electrical equipment is safe, reliable, and performs as expected.
