Why Choose the Mersen P301313 Protistor® High-Speed Fuse?
The Mersen P301313 is a specialist high-speed semiconductor fuse intended for compatible industrial power-electronic equipment. As part of Mersen’s established Protistor® product family, it is designed to help protect sensitive semiconductor components against damaging short-circuit and overcurrent conditions.
Unlike conventional general-purpose fuses, high-speed semiconductor fuses are engineered to interrupt fault currents rapidly and restrict the electrical and thermal energy reaching connected devices. This makes the P301313 suitable for compatible circuits containing power diodes, thyristors, rectifiers, GTOs and insulated-gate bipolar transistors.
The Mersen P301313 manufacturer reference enables engineers, OEMs, panel builders and maintenance teams to identify the required replacement component accurately. Its rated current, voltage, utilisation category, breaking capacity, I²t performance, dimensions and terminal arrangement should be verified against the original fuse and current Mersen technical documentation before installation.

Reliable Protection for Power Electronics
Power-semiconductor devices can suffer permanent damage within milliseconds when exposed to excessive fault current. A correctly selected high-speed fuse interrupts the fault rapidly and limits the energy reaching sensitive electronic components, helping reduce equipment damage, repair costs and unplanned downtime.
The Mersen P301313 is intended to provide dependable protection within compatible motor-control and power-conversion systems. Correct fuse selection is essential, so the required current rating, voltage rating, breaking capacity, utilisation category, I²t values, physical dimensions and connection arrangement must all be verified before ordering or installation.
Typical Applications
- Variable speed and variable frequency drives.
- Industrial rectifiers and power converters.
- Uninterruptible power supply systems.
- Motor drives and soft-start equipment.
- Industrial inverters and battery-charging systems.
- Automation and power distribution equipment.
