The LPJ-125SPI is an electrical fuse specifically designed for use in industrial and automotive applications. It is a multi-purpose, robust, fast-operating, and current-limiting cartridge fuse that combines reliable protective performance with superior protection. It is developed for a diverse range of applications, such as automotive, military, construction, and industry.

This fuse is suitable for general-purpose and industrial applications, which can be used for the protection of various loads. The LPJ-125SPI uses ferrous metal and copper alloys for a maximum continuous amperage of 125A. It also includes a special high-vibration-resistant construction, which helps to ensure a reliable operation even in vibration-prone environments. The fuse is also resistant to thermal and impact shocks.

The fuse has a robust design that ensures its high performance and excellent energy efficiency. It also has an embedded test point for visual confirmation of its service status. Additionally, the tin-plated zinc body prevents corrosion and ensures robustness during installation, and the nickel-plated contacts reduce the risk of oxidation and corrosion.

The basic working principle of the LPJ-125SPI involves a bimetallic element that consists of two metallic strips: one of copper and one of magnesium or zinc. When there is an overload or short circuit, the bimetallic element strips deflect and break the circuit, thereby preventing damage due to excessive current. The fuse is designed to provide sufficient time for the overload to be identified and corrected before operation can restart.

When selecting an LPJ-125SPI fuse for specific applications, it is important to consider the type of application, the current rating of the fuse, the voltage of the load or circuit, and the ambient temperature of the area. Additionally, it is important to choose a fuse that is compliant with relevant standards and safety regulations.

In addition to automotive, military, construction, and industrial applications, the LPJ-125SPI is also suitable for consumer electronics, hazardous area equipment, and switchgear. It is an affordable, field-tested, and not prone to failure fuse that offers reliable and long-term protection to many electrical devices.
