Fuses

5TT 3.15-R Application Field and Working Principle

A fuse is a type of device that helps to maintain the safety of an electrical system. It acts as a self-regulating switch that interrupts the circuit when it experiences an overload of current. The 5TT 3.15-R is a type of fuse that is used for medium voltage applications. The fuse was designed for use in medium-voltage networks and is suitable for use in applications where a high breaking capacity of up to 50kA is required.

The 5TT 3.15-R fuse features a wide operating temperature range and is designed for operation in either indoor or outdoor environments. It also has a high level of noise immunity due to its surge arrestor design and static operating principle. The fuse is designed to deliver reliable performance in medium-voltage circuits and is available in two distinct versions – the FUSE-4 and the FUSE-6.

The FUSE-4 version is designed for use in national or international power grids and features a voltage rating of 10kV with a breaking capacity of up to 50kA. The FUSE-6 version is designed for use in single-phase power systems and has a higher voltage rating of 10kV with a breaking capacity of up to 45kA. Both versions of the fuse are available in sizes ranging from 10mm to 35mm. The fuses are also certified to international standards IEC 60269-1 and UL 98.

When an overload of current passes through a 5TT 3.15-R fuse, the element located inside the fuse melts and breaks the circuit. This breaks the current path and prevents any further harmful overloads from occurring. The fuse element is made of a special alloy that melts quickly when heated and reacts with the energy of the overload. This reactivity allows the fuse to protect against any overcurrents without interrupting normal circuit operation.

The 5TT 3.15-R fuse is designed to provide a high level of safety and reliability in medium-voltage circuits. Its wide operating temperature range and surge arrestor design ensures that it can handle large levels of current without compromising its performance or reliability. The fuse is certified to international standards and is available in two different versions for different applications. The 5TT 3.15-R fuse is ideal for applications where a high breaking capacity is required and offers a reliable and safe solution for medium-voltage applications.
