Why Choose the Mersen G301306 Protistor® High-Speed Fuse?
The Mersen G301306 is a specialist high-speed semiconductor fuse designed to protect sensitive power electronic components against damaging overcurrent and short-circuit conditions. As part of the established Mersen Protistor® fuse range, it is suitable for industrial systems requiring rapid fault interruption and effective limitation of let-through energy.
Power semiconductors can suffer permanent damage within a fraction of a second when exposed to excessive fault current. The G301306 is engineered to operate faster than a conventional industrial fuse, helping limit the peak current and thermal energy reaching components such as IGBTs, thyristors, SCRs, diodes and rectifier modules.
Its robust industrial construction and efficient internal arc-quenching system support dependable operation in demanding power-conversion and motor-control equipment. The Mersen G301306 can be incorporated into a compatible fuse holder, busbar assembly or equipment-specific installation within drives, converters, inverters and industrial power supplies.

Reliable Protection for Industrial Power Electronics
High-speed fuses form an important part of a coordinated semiconductor protection system. During a severe electrical fault, the fuse element operates rapidly to restrict both the peak fault current and the total energy reaching the protected power module.
This fast response can help prevent secondary damage to connected equipment, reduce repair costs and shorten unplanned downtime. Correct selection should account for the circuit voltage, continuous load current, prospective fault current, semiconductor withstand characteristics and applicable electrical standards.
Typical Applications
- Variable frequency drives and industrial motor drives.
- Power converters and industrial rectifiers.
- Solar, battery and renewable-energy inverters.
- Uninterruptible power supply systems.
- Industrial power supplies and charging equipment.
- Protection of IGBT, SCR, thyristor and diode modules.
