What is EN 60255-2:2020?

The EN 60255-2:2020 is an international standard that sets out the requirements for measuring relays and protection equipment used in electrical installations. It covers a wide range of topics related to the performance, testing, and compliance of such equipment. This technical article aims to provide an easy-to-understand of this standard, breaking down its key elements and their significance.

Scope and Objectives

The scope of EN 60255-2:2020 includes both electromagnetic and static relays as well as associated circuits. The standard provides guidelines for evaluating the performance of these devices, ensuring their reliability and compatibility with different electrical systems. Its main objective is to establish common parameters and procedures for testing relay equipment, enabling manufacturers and end-users to compare products based on their performance characteristics.

Testing and Compliance

EN 60255-2:2020 specifies various tests that must be conducted to assess the performance of measuring relays and protection equipment. These tests include functionality testing, dielectric voltage withstand, temperature rise, electromagnetic compatibility, and environmental conditions. Manufacturers are required to meet specific pass/fail criteria for each test to ensure their devices comply with the standard's requirements.

Benefits and Importance

Compliance with EN 60255-2:2020 offers several benefits to manufacturers, suppliers, and end-users. Firstly, it guarantees the quality and reliability of the relay and protection equipment, minimizing the risk of malfunctions or failures in critical electrical systems. Secondly, it enables fair competition between manufacturers by providing standardized performance evaluation criteria. Lastly, compliance ensures that the equipment meets recognized industry standards, facilitating its acceptance and adoption in national and international markets.
