3SBP 300

3SBP 300 application field and working principle can be divided into three parts：Application, Construction and Performance.

Application

The 3SBP 300 is a well known fuse link. It is used for current limiting in high-voltage feeders as motor circuit protection. It can be applied in many installations, especially those with industrial, military and aerospace loads. The purpose of the 3SBP 300 is to protect electrical systems against both short-circuits and overloads. It is designed to withstand over-voltage and against damage due to ambient air conditions. Its use is not limited to the industrial sector, it can also be used in military and aerospace applications.

Construction

The main components of the 3SBP 300 fuse link are the link, the protective capacitor, the arcing resistor and the protective contact. The link is made of silver, and the protective capacitor is composed of two silver contact surfaces. The arcing resistor is composed of two coils and a ceramic base. The protective contact is composed of a metal contact and a silicone rubber protective band. The components are assembled and tested before they are shipped out.

Performance

The performance of the 3SBP 300 is based on its ability to trip quickly and properly. It is tested in a laboratory under different current conditions to determine its faults and performance. The 3SBP 300 fuse link has proven itself to be very reliable, with a short time to trip from both open and closed circuits. It is also designed to protect against arcs and electrical faults. The 3SBP 300 fuse link is also designed to be resistant to high levels of temperature and humidity. The fuse can withstand over-voltage and prolonged over-temperature.

The 3SBP 300 fuse link is considered to be one of the most reliable and safe fuses available in the market. It is well suited for applications where a reliable protective device is needed. It is designed to withstand the high demands of industrial applications, military and aerospace applications, as well as other high-voltage uses.
