What is the difference between BS1361 and BS1362

BS1361 and BS1362 are two standards used in electrical installations to ensure safety and prevent accidents. While both standards have similar objectives, there are important differences that distinguish them from each other. In this article, we will delve into the technical aspects of each standard and explore their unique features.

BS1361: The Fuse Standard

BS1361 is a British Standard for fuses used in domestic and industrial electrical circuits. It specifies the requirements for different types of cartridge fuses, including their dimensions, characteristics, and performance parameters. The standard covers aspects such as breaking capacity, voltage ratings, and current ratings.

Fuses certified under BS1361 are designed to protect electrical circuits from overcurrents and short circuits. They are commonly used in applications where the fault levels are relatively low. These fuses are characterized by their compact size and wide range of current ratings, making them suitable for various installations.

BS1362: The General-Purpose Cartridge Fuse Standard

Unlike BS1361, BS1362 is a general-purpose cartridge fuse standard that is primarily used in domestic applications. This standard covers a wider range of fuses, including those used in plugs, socket outlets, and consumer units. It provides specifications for various types of fuses, such as full-range fuses, semi-enclosed fuses, and miniature circuit-breaker fuses.

BS1362 fuses are designed to provide protection against overloads and short circuits in residential electrical systems. They are typically rated for lower breaking capacities compared to BS1361 fuses, as domestic installations generally have lower fault levels. These fuses are widely available and can easily be replaced, making them convenient for homeowners.

Key Differences

The main difference between BS1361 and BS1362 lies in their application and specific requirements:

Scope: BS1361 focuses on fuses used in industrial applications, whereas BS1362 primarily addresses fuses used in domestic settings.

Ratings: BS1361 fuses have higher breaking capacities compared to BS1362 fuses, as industrial installations often have higher fault levels.

Availability: BS1362 fuses are more readily available for homeowners, and they can be easily purchased from local hardware stores.

In conclusion, both BS1361 and BS1362 play a crucial role in electrical safety. While BS1361 is geared towards industrial applications and has higher performance requirements, BS1362 is specifically designed for domestic use. It is important to understand the differences between these standards to ensure the proper selection and installation of fuses in different electrical systems.
