Electrical, Specialty Fuses

MV155F1DBS25E is an electrical specialty fuse. It is a single-phase, 125V panelboard fuse that uses direct connected links to reduce strain on surrounding components or assemblies. The MV155F1DBS25E has a molded case with a series of metal needles embedded in it.

The MV155F1DBS25E fuse is an ideal choice for applications with higher amounts of energy loading and/or fault protection requirements. It can be used in a variety of applications, such as commercial warehouses, industrial plants, and residential panelboards.

Working Principle

MV155F1DBS25E fuses operate using a principle known as “thermal breakover”. This principle works by using a metal wire, called the "fuse wire”, that is embedded in the fuse body. This wire acts like a heater and melts when the current in the circuit becomes higher than the fuse’s rated ampere rating. When the fuse wire melts, it causes an arc to form in the air between the two surfaces of the fuse and the arc is then suppressed in a process of “quenching” that eliminates the arc. This process results in the breaking of the circuit.

When the fuse is subjected to overload, it is designed to break the current in the circuit before it can cause any damage to the components or the wiring. The thermal breakover principle works by causing the fuse wire to heat up if the current in a circuit becomes greater than the rated current. This heat will cause the fuse wire to melt, thus breaking the circuit.

The MV155F1DBS25E fuse can be used in a variety of applications and is designed to provide a fast and reliable response to protect equipment and wiring from damage due to overcurrents. Most importantly, the fuse is designed to respond fast and accurately when it detects an overcurrent situation, which helps to ensure the safety of personnel and equipment in the area.

Conclusion

The MV155F1DBS25E is an electrical specialty fuse that can be used in a number of applications, from residential panelboards to commercial warehouses and industrial plants. The fuse utilizes a thermal breakover principle which causes the fuse wire to heat up and melt when the current in the circuit becomes higher than the fuse’s rated ampere rating. This process helps to protect equipment and wiring from damage due to overcurrents.
