Why Choose the Mersen V300582 High-Speed Semiconductor Fuse?
The Mersen V300582 is a high-performance Protistor® square body semiconductor fuse engineered to provide exceptional protection for sensitive power electronic devices. Designed for demanding industrial environments, this ultra-fast acting fuse helps safeguard semiconductors such as IGBTs, thyristors, diodes and MOSFETs against damaging short circuits.
As part of the trusted Mersen Protistor® Size 30 aR series, the V300582 delivers rapid fault interruption while maintaining low let-through energy (I²t). This helps maximise equipment uptime, minimise costly component damage and improve the overall reliability of power conversion systems.
Rated at 450 A with a 690 V AC (IEC) / 700 V AC (UL) voltage rating, the V300582 is ideally suited for industrial drives, UPS systems, inverters, motor drives and renewable energy equipment. Its square body construction with striker indicator allows easy integration into modern protection systems.
