Why Choose the Mersen P082468 High-Speed Semiconductor Fuse?
The Mersen P082468 is an ultra-rapid Protistor® semiconductor fuse-link developed to protect sensitive power electronic components against damaging short-circuit currents. Its fast operating response and effective current limitation make it suitable for industrial equipment containing diodes, thyristors, rectifiers, IGBTs and other semiconductor devices.
Identified by the catalogue designation 2,5 URGG 36/200, the P082468 features an aR partial-range operating characteristic specifically intended for semiconductor protection. By restricting peak fault current and let-through energy, the fuse helps reduce electrical, thermal and mechanical stress within valuable power conversion equipment.
With a rated current of 200 A and a rated voltage of 250 V AC, the Mersen P082468 is suitable for variable frequency drives, industrial rectifiers, converters, inverters and power supplies. Its compact 36 × 27 mm British Standard fuse-link format and bolted terminal arrangement provide a secure, space-efficient solution for demanding industrial installations.

Rapid Protection for Power Semiconductor Equipment
The Mersen P082468 is designed to interrupt dangerous fault currents before excessive energy reaches sensitive semiconductor components. Its ultra-rapid operation limits peak current and total let-through energy, helping reduce damage to power modules, conductors and associated electrical equipment.
As an aR-class fuse-link, the P082468 provides partial-range protection specifically against semiconductor short-circuit currents. Suitable supplementary overload protection should be included where the installation requires complete protection against both overload and short-circuit conditions.
Typical Applications
- Variable frequency drives and industrial motor controllers.
- Industrial rectifiers and power converters.
- Inverters and power conversion systems.
- Uninterruptible power supply equipment.
- Industrial battery chargers and DC power supplies.
- Semiconductor-controlled machinery and automation systems.
Secure and Space-Efficient Installation
The compact square-body design allows the Mersen P082468 to be installed within compatible fuse assemblies where panel space is limited. Its bolted connections provide a secure electrical interface that is well suited to industrial equipment exposed to high currents, vibration and repeated operating cycles.
For correct protection performance, the replacement fuse should match the required current rating, voltage rating, operating class, dimensions and terminal configuration. Circuit conditions and semiconductor withstand values should always be checked before installation.
