Why Choose the Mersen V087855 Protistor High-Speed Fuse?

The Mersen V087855, catalogue number FD20GC150V1, is an ultra-fast cylindrical semiconductor fuse designed to protect sensitive power electronic equipment against damaging overcurrents and short-circuit faults. Part of the Mersen Protistor® 20 × 190 mm gR (gRC) series, it is engineered for high-voltage DC systems where rapid fault interruption and low let-through energy are essential.

Power semiconductor devices can suffer permanent damage within milliseconds when exposed to excessive current. The V087855 helps limit the thermal and mechanical energy reaching protected components, reducing the risk of extensive damage to converters, rectifiers, inverters and associated control equipment.

With a rated current of 1 A and a rated voltage of 1500 V DC, this fuse is suitable for sensitive low-current circuits operating within demanding high-voltage installations. Its 20 × 190 mm cylindrical format allows installation in compatible fuse clips and holders used throughout industrial, transport and power conversion applications.

Reliable Protection for High-Voltage DC Equipment

High-speed fuses are engineered to operate significantly faster than general-purpose circuit protection devices. This rapid response limits the electrical energy passing through sensitive semiconductor components during a fault and helps prevent cascading damage within power electronic assemblies.

The Mersen V087855 combines a high 1500 V DC rating with a low 1 A current rating, making it particularly suitable for sensitive control, monitoring and auxiliary circuits within high-voltage equipment. Correct fuse-holder selection and coordination with the protected semiconductor device are essential for safe and dependable operation.

Typical Applications

  • High-voltage DC power conversion equipment.
  • Railway traction and auxiliary circuits.
  • Industrial rectifiers and converters.
  • Power inverter protection.
  • Semiconductor control circuits.
  • Battery energy storage equipment.
  • Renewable energy conversion systems.
  • Industrial automation and power distribution assemblies.
