The Mersen N330246 is a high-speed NH size 00 semiconductor protection fuse engineered to provide ultra-fast overcurrent protection for power semiconductors, converters, drives and industrial power electronics. As part of the trusted Mersen Protistor® high-speed fuse range, it is specifically designed to protect sensitive semiconductor devices such as IGBTs, thyristors and diodes from damaging short-circuit currents.
Featuring an ultra-fast aR operating characteristic, the N330246 delivers exceptional current limiting performance, helping minimise fault energy and extend the service life of expensive power electronic equipment. Its robust square body construction and integrated striker indicator simplify installation and maintenance in demanding industrial environments.
With a 450 A current rating, 600 V AC operating voltage and DIN NH size 00 format, the Mersen N330246 is ideally suited for industrial variable speed drives, UPS systems, inverters, converters and OEM power control equipment requiring dependable semiconductor protection.
High-speed semiconductor fuses are specifically designed to interrupt extremely high fault currents before sensitive power electronic components can be damaged. The Mersen N330246 delivers rapid fault clearance with very low let-through energy, helping maximise equipment availability and minimise repair costs.
Its proven Protistor® design makes it suitable for protecting modern industrial power conversion systems operating under demanding electrical conditions where conventional fuses cannot provide adequate semiconductor protection.
