Why Choose the Mersen FR10GR69V20 Protistor® Semiconductor Fuse?

The Mersen FR10GR69V20, also identified by item number E1014580, is a high-speed Protistor® cylindrical semiconductor fuse engineered to protect sensitive power electronic equipment against damaging overload and short-circuit currents. Its compact design, rapid operation and high interrupting capacity make it suitable for industrial systems where dependable semiconductor protection is essential.

This fuse has a rated current of 20 A and an IEC rated voltage of 690 V AC. Its gR full-range operating characteristic provides protection against both small overload currents and high short-circuit currents, helping safeguard semiconductor devices throughout a broad range of fault conditions.

With a standard 10 × 38 mm cylindrical format, the FR10GR69V20 can be installed in compatible fuse clips and cylindrical fuse holders. Its ceramic body, silver-plated copper ferrules and low I²t performance support reliable operation in inverters, uninterruptible power supplies, variable-speed drives and other industrial power-conversion equipment.

Key Advantages

  • High-speed semiconductor fuse designed for power electronics.
  • 20 A rated current for compact industrial protection circuits.
  • 690 V AC IEC voltage rating for demanding applications.
  • gR full-range characteristic protects against overloads and short circuits.
  • Low I²t performance helps limit energy transferred to semiconductor components.
  • 160 kA breaking capacity for dependable high-fault-current interruption.
  • International 10 × 38 mm cylindrical format.
  • Excellent cycling capability for applications with changing electrical loads.

Key Features

  • Mersen Protistor® 10 × 38 gR series.
  • 20 A rated current.
  • 690 V AC rated voltage according to IEC.
  • gR high-speed, full-range fuse characteristic.
  • 160 kA AC breaking capacity.
  • 39 A²s pre-arcing I²t.
  • 245 A²s clearing I²t at rated voltage.
  • Ceramic insulating body for industrial durability.
  • Silver-plated copper ferrule terminals.
  • Clip-mounted cylindrical construction.

Reliable Protection for Industrial Power Electronics

High-speed fuses such as the Mersen FR10GR69V20 are designed to interrupt fault currents before excessive thermal energy can damage semiconductor devices. Its current-limiting operation and low I²t values help protect components such as diodes, thyristors, rectifiers and insulated-gate bipolar transistors.

Unlike partial-range semiconductor fuses, the gR characteristic provides full-range protection against both overload and short-circuit conditions. This makes the FR10GR69V20 a versatile protection solution for compact power-conversion equipment, industrial motor controls and automation systems operating at up to 690 V AC.

Typical Applications

  • Small industrial inverters and power converters.
  • Uninterruptible power supply systems.
  • Variable-speed and variable-frequency drives.
  • Industrial motor-drive equipment.
  • Rectifiers and semiconductor power supplies.
  • Power semiconductor protection circuits.
  • Automation and machine-control equipment.
  • Industrial power-electronic assemblies.
