What is EN 62305-4:2020 ?

EN 60255-26:2020 and EN 60664-3:2020 are two important technical standards that are critical to ensuring the safety and reliability of electrical power systems. EN 60255-26:2020 specifies the performance requirements and test procedures for protective relays, while EN 60664-3:2020 provides guidelines for insulation coordination for low-voltage systems.

EN 60255-26:2020 is a professional technical standard that is used to ensure the proper functioning and accuracy of protective relays used in electrical power systems. It specifies the performance requirements and test procedures for these relays, which are designed to prevent overloads, short circuits, and voltage fluctuations. By following this standard, manufacturers can design relays that meet certain performance criteria, making them reliable and effective in protecting power systems from various abnormalities.

EN 60664-3:2020, on the other hand, is an important technical specification that is used to ensure the safe use of electrical equipment and systems. It provides guidelines for insulation coordination for equipment within low-voltage systems, which is critical for preventing electrical shock hazards and reducing the risk of fire caused by electrical malfunctions.

The primary purpose of EN 60664-3:2020 is to ensure the safety of electrical equipment and systems by defining specific insulation requirements and procedures. It aims to prevent electrical shock hazards and reduce the risk of fire caused by electrical malfunctions. The standard establishes consistent guidelines that manufacturers, engineers, and other industry professionals can follow to achieve safe and reliable operation of electrical equipment.

EN 60255-26:2020 and EN 60664-3:2020 are both important technical standards that are critical to ensuring the safety and reliability of electrical power systems. By following these standards, professionals in the electrical engineering field can design and operate protective relays and electrical equipment safely and effectively.
