Reliable Protection for Industrial Power Electronics
Power semiconductor devices require specialist protection because conventional industrial fuses often operate too slowly during high-energy fault conditions. High-speed Protistor® fuses rapidly interrupt fault currents, helping to reduce thermal stress and extend the service life of valuable electronic equipment.
Correct fuse selection should always be based on the complete manufacturer reference together with the equipment's required voltage, current rating, breaking capacity and operating characteristics to ensure safe and reliable protection.
Typical Applications
- Variable frequency drives.
- Industrial motor control systems.
- Power converters and rectifiers.
- UPS systems.
- Renewable energy inverters.
- Industrial automation equipment.
