LPJ-2-1/2SP electrical specialty fuses are sturdy and reliable devices that are used to protect electrical circuits and equipment from overloads and short circuits. They are usually installed in applications such as buses, elevators, process controls, HVAC, computers, and other industrial and commercial applications. This type of fuse is UL listed and UL recognized, and is ideal for use in both low voltage and high voltage applications.

LPJ-2-1/2SP Product Features

LPJ-2-1/2SP is available in both 10 amp and 25 amp ratings. It provides superior protection from short circuits because it very quickly opens the circuit in the event of a fault. The fuse has a time- delay design, meaning it will stay closed even when subjected to overloads, allowing the electrical circuit to stay hot and functioning for a predetermined amount of time. This helps to protect the circuit while allowing full current flow during normal operation.

The device also utilizes a patented system design, allowing for added flexibility in installation and repair. This is because the signal circuit and current-carrying leads are housed in the same holder. Additionally, the patented system design makes it easier to replace components, as all parts are integrated into one unit. Another great feature of the LPJ-2-1/2SP is its stainless steel contacts, which are resistant to corrosion and oxidation.

Another important safety feature of the LPJ-2-1/2SP is its built-in anti-vibration design. This allows the fuse to remain intact and effective in even the most extreme environments. The design also makes the device more durable, making it able to withstand the repetitive operations often associated with industrial and commercial applications, such as machines in factories.

LPJ-2-1/2SP Working Principle

LPJ-2-1/2SP utilizes a bimetal principle of operation. This means that when an electrical current passes through the fuse, the contact bimetal is forced to move in response to the temperature change. This movement causes the contact trip spring to be compressed and the contacts to open, thus interrupting the circuit downstream. The device is designed to operate at 75% of rated current, allowing the current to be "carried" by the fuse for a period of time before the contacts break, so as to ensure a safe disconnection.

The LPJ-2-1/2SP also contains an indicator disk, which is a pressure-sensitive component that helps to quickly locate a malfunctioned part. It works by bending its shape in response to the temperature change inside the device. When the indicator disk is bent, it will show an indication of increased temperature, alerting the user that there is an issue with the fuse.

Because of its high efficiency, low cost, and reliable protection, the LPJ-2-1/2SP is a popular choice for electrical manufacturers. It helps to reduce the risks associated with overcurrent and short circuit protection while still allowing for full current flow during normal operations.
