LPJ-250SP Application Field and Working Principle

The LPJ-250SP is a specialty fuse designed for different components used in electrical and lighting systems. It is manufactured by Littelfuse, Inc., and is compatible with standard type SP and SPC fuses. The LPJ-250SP is designed to prevent system overloads from occurring due to short-circuit, overheating, and overloads. It features a 250VAC, 400VDC rated voltage, with an interrupting rating of 10,000A at 250VAC.

The LPJ-250SP is used in a variety of different applications. It is typically used to provide protection in electrical control boxes, transformers, junction boxes, machinery panels, power adapters, and other electrical systems. It is also commonly used in residential, commercial, industrial, and transportation applications. In addition, the LPJ-250SP is UL listed for use in hazardous locations.

Working Principle

The LPJ-250SP fuse works on the principle of thermal expansion. When there is an excessive current flow that exceeds the rated current for the fuse, the metal spool inside the fuse will heat up and expand. This causes the metal to expand and break the circuit. The fuse is then able to effectively shut down the system and protect against further damage. The fuse also has a “thermal cut-off” feature, which allows it to shut down the system if the temperature of the metal spool exceeds a certain set point.

The LPJ-250SP fuse also has a “high current” feature, which allows it to shut down the system when a certain amount of current is exceeded. This feature is particularly useful for applications where the device may be prone to short circuits or current overloads. The fuse also has an “inverse time” delay feature, which delays the shutdown of the system by a certain amount of time. This delay allows the fuse to more effectively protect the system from damage caused by current overloads.

The LPJ-250SP also has a “voltage surge” feature, which helps protect the system against unexpected voltage rises. This feature is particularly useful for applications that are likely to experience unexpected spikes in voltage. The fuse also has a “sulfur-resistant” feature, which helps protect the system against corrosion from sources such as acid rain or sulfur emissions.

Overall, the LPJ-250SP fuse is an effective protection device for electrical systems, especially in hazardous areas where the risk of an unexpected surge is high. It is designed to protect the system from overloads, short circuits, and other issues caused by excessive current flow. By using the “thermal cut-off”, “high current”, “inverse time”, and “voltage surge” features, the LPJ-250SP fuse provides comprehensive protection against electrical damages.
