SPJ-4E200

The SPJ-4E200, an electrical switching device manufactured by Sermatech International, is a specialty fuse that is widely used in industrial, commercial, and residential applications. It is designed for use with low and medium voltage circuits and offers excellent reliability, safety, and performance.

Working Principle

The SPJ-4E200 utilizes a process of thermal overload protection by utilizing a thermal heating element to open and close the electrical contacts of the switch. The thermal overload protection works by detecting current overload in a circuit and reducing the flow of electricity to the appliance or device to prevent further damage or fire. The heating element will usually respond to a current overload very quickly and open the contacts of the switch, thus protecting the circuit and preventing further damage. The thermal overload protection can also be set to different levels, depending on the specific application.

Applications

The SPJ-4E200 is primarily used in industrial, commercial, and residential applications, such as in mining, power plants, manufacturing, commercial buildings, homes, and industrial equipment. The SPJ-4E200 can also be found in switchgear, transformers, motor controls, circuit protection, and other electrical components. The device is extremely reliable and is capable of handling high levels of current.

The SPJ-4E200 is well-suited for applications requiring frequent switching without significant risk of damaging the components or the circuit. The SPJ-4E200 is capable of controlling and switching high currents at a wide range of temperatures and is a reliable device for medium and low voltage applications.

Advantages

The SPJ-4E200 has several other advantages that make it popular for a variety of applications and industries. This device is very energy efficient, as it uses less power than other switches when activated. It has a long life span, as it can switch up to 10,000 times depending on the application and environment. Additionally, the device is very reliable due to its high-quality components and its ability to quickly detect and prevent current overloads. Finally, the SPJ-4E200 is very affordable, making it an excellent choice for any application.
