The SPJ-7K450 Electrical Specialty Fuse is a high temperature, time delay fuse used in the protection of AC circuits. It is designed to detect and protect against both overcurrent and overvoltage in single-phase and three-phase AC systems. It is a highly reliable fuse with a breaking capacity of 7,500 amps and a rated melting I2t of 315 at 450 volts.

This fuse has a wide range of applications, including motor protection, control panels, lighting systems, air conditioning systems, industrial equipment, and other general purpose applications. It can also be used as a primary protection device for high-current applications in applications such as motor protection and transformer protection.

The working principle of SPJ-7K450 is based on current limiting. This fuse is equipped with a high temperature, metal-oxide element. When the fuse is overloaded, the element will heat up and vaporize, causing a sudden decrease in current that will safely blow the fuse. The high melting I2t of the fuse prevents it from further heating up, thus protecting the circuit.

The SPJ-7K450 has an excellent response time of 30 ms, which ensures quick response and protection for your circuit. The fast-acting response time enables the fuse to protect against dangerous overloads and shorts in the circuit in the shortest amount of time possible.

The SPJ-7K450 is also highly reliable and can be safely used in different kinds of applications up to its rated voltage and current values. It also features a temperature compensation feature that allows it to perform reliably at different temperatures. The fuse is also designed to work under continuous as well as short circuit conditions, protecting the circuit from potential damage that could be caused by an overload or short circuit.

The SPJ-7K450 Electrical Specialty Fuse is a highly reliable, fast-acting, and temperature-compensated fuse that is designed for use in a wide variety of applications. Its high melting I2t allows it to protect against dangerous overloads and shorts in the circuit in the shortest amount of time possible. This fuse is an excellent choice for applications such as motor protection, control panels, lighting systems, air conditioning systems, and industrial equipment.
