Introduction

Users miniature fuses hope that all involved in standard miniature fuses, recommendations and other documents should have the same standard order number so in reference to fuses in other specifications, such as equipment specifications.

In addition, the use of a standard number, and is divided into several parts, in favor of the new standards, because the provision contains general requirements on Need not repeated.

Miniature fuses

Part 10. User's Guide

1 Scope

This section specifies the nature of miniature fuses, fuse different types of applications, I2t limit protection and pulse operation, the DC should with, fuse holders, performance, technical requirements affected by the ambient temperature at extra-low voltage.

This section applies to regularly scheduled within the protection of electrical household devices, electronic equipment and components used in small fuse, that is GB 9364.2, GB 9364.3 and GB 9364.4 fuse prescribed.

This section applies to the fuse holder in line with GB 9364.6 of miniature fuses. This section does not apply to scheduled special conditions (for example.

Corrosive or explosive atmospheres) of electrical fuse devices under use.

The purpose of this guide is to give users about important properties of compact fuse holder and fuse mini fuse, and gives some of the use of melt Off the guide member.

Note 1. If the fuse prove GB 9364 performance does not meet the requirements, the reference GB 13539.

Note 2. Due to differences in design, the same type and rating fuse may have different voltage drop and different properties. Therefore, in practice, when their use in low-voltage circuit device, especially in combination with a lower rated current fuse, they may not be interchangeable.

Note 3. Contact the manufacturer for more information.

3 Property, miniature fuses

Small fuse provides short circuit and overload effect continued protection and fault protection element and the front end of the conductor, the back-end fault isolation Branch fault circuit. Disconnect the fuse also acts as a diagnostic tool to help identify the location of the fault. These properties include.

--- Diverse forms of physical structure. a small fuse on the physical structure of a variety of choices. For example, some fuse can be installed to clip and fuse holder, or inserted into the tube holder can be easy to replace. Some type of surface mount or through perforations Mount mounted to wave or reflow soldered to the printed circuit board.

--- Low cost and very small size. suitable for mounting on small devices, small fuse circuit provides a very good protection.

--- A wide range of features. miniature fuses commonly used in lower than expected short-circuit current 1500A electronic devices. Small melting Breaker has a very wide range of properties, from the (very) quick action type to the (long) delay type. The latter type is very useful, Because they can withstand the inrush current when connected to the circuit, but in the continuous overload will disconnect.
