The SPJ-5E275 is an energy-limiting Class J fuse designed to provide circuit protection in compliance with the requirements of UL Standard 248-14. It is used in applications where space is at a premium and extra protection is needed, such as in solar installations. The SPJ-5E275 is equipped with a superior one-time trip feature allows it to be used in applications that require fast trip times. The fuse also has a high interrupting rating, allowing it to be used in circuits with higher voltage and current levels.

The SPJ-5E275 is designed to protect against short circuits, ground faults, and overloads on branch circuits. It provides protection for small motors, transformers, and other equipment. The SPJ-5E275 is UL Listed for use up to 277 Vac and 30Vdc. It has a time-delay characteristic to allow for motor start-up current. The fuse is rated for 10kA interrupting rating.

The SPJ-5E275 is designed with a durable molded case that has a nickel-plated brass end cap, providing additional durability. The fuse is designed to be easily installed in standard fuse holders and has a built-in handle for easy removal. The fuse is also designed to be vibration resistant, providing protection in high-vibration applications.

The working principle of SPJ-5E275 is based on a temperature dependent bimetal strip, which will open or break a circuit based on its thermal response to an overcurrent. The bimetal strip is composed of two different types of metal with different coefficients of thermal expansion- one metal expands faster when heated compared to the other. When there is an overcurrent, a magnetic force pulls the expanded metal strip towards the magnet, opening or breaking the circuit.

The design of the SPJ-5E275 also enables it to protect against surges. The one-time trip feature, which is triggered by an overvoltage, limits the number of tripping cycles. This feature will also protect the fuse from false trips and potential damage to the components it is protecting. This feature is also beneficial in applications where frequent on/off switching of the circuit is expected.

The SPJ-5E275 is an ideal solution for a wide variety of applications. It is designed to provide reliable, fast-acting protection in harsh environments. It is available in a wide range of amperage ratings and can be used with AC, DC, and high-frequency supplies. It is also suitable for applications where low overvoltage protection is needed.
