What is IEC 60287 ?

IEC 60287: A Technical Article on High-Voltage Current-LIMITING Fuses

High-voltage current-limiting fuses are an essential component of electrical systems. They are designed to protect equipment and installations from overcurrents and short circuits, ensuring the safety and reliability of the system. IEC 60287, also known as "High-voltage fuses - Current-limiting type," is an international standard published by the International Electrotechnical Commission (IEC) that provides guidelines and specifications for these fuses.

In this technical article, we will delve into the principles, requirements, and applications of IEC 60287, giving you a comprehensive understanding of this critical component in electrical systems.

Principles and Requirements

IEC 60287 is divided into four parts, each covering a different aspect of high-voltage current-limiting fuses. These parts are as follows:

Principles and requirements for general purpose fuses

Principles and requirements for high-voltage current-limiting fuses

Principles and requirements for medium-voltage current-limiting fuses

Principles and requirements for low-voltage current-limiting fuses

Each part of IEC 60287 provides guidelines and specifications for the design, manufacture, testing, and certification of high-voltage current-limiting fuses. These guidelines cover various aspects, including the materials used, the dimensions of the fuses, the operating characteristics, and the testing procedures.
