SPJ-7E600

Introduction

The SPJ-7E600 is an electrical specialty fuse made by A.B.Chance Company that is used to protect electrical circuits. It is particularly suited to high voltage applications and is designed to detect and interrupt any faults on the line. It is easy to install, reliable in operation and has a dual function: it can act as a fuse-link for short circuit protection, or as a surge arrester for overvoltage protection.

Features

The SPJ-7E600 has two main features. Firstly, it has a dual terminal connection that allows for a convenient way of connecting the fuse to the electrical circuit. Secondly, it has a quick-acting fuse cartridge that is designed to detect and interrupt any faults on the line. The fuse cartridge has a wide range of amperage ratings, from 5A to 100A, and is able to operate at low ambient temperatures.

Technial Specifications

The SPJ-7E600 has a voltage rating of 600V with a current rating of 200A, which makes it suitable for a wide range of applications. It has a temperature range of -40°C to +65°C and can be used in both indoor and outdoor environments. The fuse meets all relevant safety standards and is designed to meet the requirements of UL508, UL817 and CSA 22.2.

Applications

The SPJ-7E600 is primarily used to protect electrical circuits from short-circuits, overvoltage and overcurrent faults. It is suitable for a wide range of industrial and commercial applications, such as power supplies, UPS systems, emergency lighting systems, motor applications, electrical machines and other hazardous locations. The fuse is especially suitable for high voltage applications due to its ability to withstand high temperatures.

Working Principle

The SPJ-7E600 is made up of an outer metal housing and an inner cartridge containing the fuse link. The fuse is connected to the electric circuit by two terminals. When a fault is detected, the current passes through the fuse link and causes it to heat up. When the temperature rises above the melting point of the fuse link, it melts and the current is interrupted, thus protecting the circuit from further damage.

Conclusion

The SPJ-7E600 is an electrical specialty fuse designed to protect electrical circuits from short circuit, overvoltage and overcurrent faults. It has a dual terminal connection and a quick-acting fuse cartridge that offers protection in a wide range of applications. The fuse has a voltage rating of 600V and a current rating of 200A. It is reliable in operation and meets all relevant safety standards.
