What is EN 60127-2:2020?

EN 60127-2:2020 is an international standard that sets the requirements for miniature fuses. It was published by the European Committee for Electrotechnical Standardization (CENELEC) and has been widely adopted by manufacturers and users of electrical equipment around the world. This standard specifically focuses on subminiature fuses, also known as "small glass tube fuses," used in various applications such as consumer electronics, automotive, and industrial sectors.

Functionality and Features

The key function of EN 60127-2:2020 compliant fuses is to protect electrical circuits from overcurrents and short circuits. These fuses provide reliable protection by interrupting the current flow when it exceeds a preset threshold. They are designed to prevent damage to the circuit and other connected components, thereby ensuring safety and preventing potential hazards such as fire or electric shock.

These miniature fuses are characterized by their small size and cylindrical shape, typically made of a glass tube with metal end caps. They offer a compact and efficient solution for circuit protection in space-constrained applications where traditional fuses are not suitable due to their larger size.

Compliance and Testing

EN 60127-2:2020 establishes the general requirements for the construction, performance, and marking of subminiature fuses. It specifies parameters such as rated voltage, rated current, breaking capacity, and temperature rise limits. Manufacturers must ensure that their products comply with these specifications and conduct testing to verify the performance characteristics of the fuses before they are marketed.

Compliance with this standard ensures that the fuses meet the necessary safety and quality standards, enabling compatibility and interchangeability between different brands and models. Additionally, it provides assurance to consumers and regulatory authorities regarding the reliability and performance of these miniature fuses.

Applications and Benefits

EN 60127-2:2020 compliant fuses find applications in a wide range of electrical and electronic devices. They are commonly used in power supplies, control circuits, lighting equipment, communication systems, and automotive electronics, among others. Their small size enables their integration into densely populated circuit boards, making them ideal for modern compact devices.

The benefits of EN 60127-2:2020 compliant fuses include enhanced safety, protection of equipment, and prevention of costly damages. Implementing these fuses in electrical systems ensures reliable circuit protection, reducing the risk of fires and malfunctions caused by overcurrents. Moreover, their standardized nature allows for easy replacement and ensures the availability of compatible fuses in the market.
