SPJ-7E450 Application Field and Working Principle

Introduction

The SPJ-7E450 model is a typical automotive fuse, with a rated voltage of 12V and a current range of 0-450A. The new model is designed to provide excellent protection on the most popular automotive and commercial vehicles, and it is widely used in many specialized applications as well. This article will introduce the application field and working principle of SPJ-7E450 model.

Application Field

The SPJ-7E450 model can be used in a wide range of automotive applications, including automobiles, motorcycles, trucks, Commercial Vehicle, off-road vehicles, SUVs, and more. It can also be used in other applications such as power supplies, current limiting switches, lighting, audio systems, and battery chargers. This model has been designed with superior protection capabilities and is ideal for use in many of the most demanding automotive environments.

Working Principle

The SPJ-7E450 model works by opening an electrical circuit when the current passing through its terminals exceeds the predetermined protection limit. This is done by melting the metal strip or wire within the fuse body, resulting in an instantaneous interruption of the current. This immediate action helps to prevent further damage to the system due to an overload of current.

The SPJ-7E450 model is designed with a reset-type fuse link that allows the device to be reset after it trips. The reset type fuse contains an internal bistable switch, which is designed to remain in an open state even after the fuse has tripped. When the fault in the circuit has been corrected, the switch can be closed without the need to remove or replace the fuse itself.

Conclusion

The SPJ-7E450 model is an ideal automotive fuse for a wide range of applications, and it is designed to provide excellent protection for the most popular vehicles. It is compatible with 12V rated voltage and 0-450A current range. Moreover, it has a reset-type fuse link that allows it to be reset after tripping and without the need to replace or remove the fuse.
