3SB 375-R

Fuses are safety devices designed to protect electrical circuits from unexpected high currents and overheating. Fuses can be found in most electrical and electronic devices, from simple appliances to complex equipment. The 3SB 375-R is a fuse type designed for medium voltage applications in three-phase power systems. This type of fuse has found widespread application in the industrial, commercial, and military sectors.

The 3SB 375-R is a medium voltage time-delay fuse designed for continuous current carrying and withstands intermittent high overcurrents before reactivating. It utilises long-term current-limiting protection to limit short circuit currents and prevent damage to electrical equipment. This fuse is specifically designed for use in three-phase power systems, which are used in locations such as industrial factories, power plants, hospitals, and military bases.

The 3SB 375-R fuse operates on the principle of inverse-time delay. This means that when an overload of the wiring system is detected, the fuse will react to reduce the current flow through the wires. The time delay is set based on the system application, allowing larger currents to flow for a limited time before the fuse trips. The fuse is designed to be able to withstand multiple trips and reset without failure.

The 3SB 375-R featured a wide range of operating temperatures from -40°C to +70°C, making it suitable for use in harsh environments. It has a quick-acting ad instruction time of 0.02 seconds, providing fast protection against short circuits. This fuse features a low voltage drop and high breaking capacity to provide maximum protection for the wiring system. It also has a long-term performance and is easy to install and maintain.

The 3SB 375-R fuse is an ideal safety device for three-phase power systems. It provides protection against current overloading, short-circuiting, and other potential safety hazards. The fuse is highly reliable and able to withstand repeat trips without failure. This makes it suitable for industrial, commercial, and military applications, where safety and performance are critical.
