NEW ARRIVAL: Siemens SITOR 3NE3340-8 Semiconductor Fuse Now in Stock

Model Description

We are pleased to announce the immediate availability of the Siemens SITOR 3NE3340-8 semiconductor fuse link, a critical protection component for power electronics applications. This NH2-size fuse features slotted blade contacts with front indicator and delivers 900A current rating at 690V AC, specifically designed for protecting power semiconductors from short-circuit conditions. The fuse's extra-fast acting characteristic (aR operational class) ensures reliable shutdown within milliseconds, preventing catastrophic failure of expensive IGBTs, MOSFETs, and diodes in frequency converters, UPS systems, and motor soft starters. With mounting dimensions of 110mm, the 3NE3340-8 installs seamlessly in LV HRC fuse bases, switch disconnectors, or can be directly bolted to busbars via M10 screws for optimal thermal performance. The compact design measures 149mm height x 59mm width x 70mm depth, providing space-efficient protection in control panels and power distribution cabinets.

Key Features

The 3NE3340-8 delivers exceptional protection performance with 100kA rated switching capacity, safely interrupting extremely high fault currents in semiconductor-based systems. Operating temperature range spans -20°C to +50°C, with storage capability from -40°C to +80°C, ensuring reliability across industrial environments. Power loss at rated current measures 165W per pole, optimized for thermal management in densely populated enclosures. The slotted blade contacts feature silver plating for minimal contact resistance and reliable current transfer. Compliance with IEC 60269-4, UL, and CCC certifications enables global deployment. The front-mounted mechanical status indicator provides clear visual tripped/open circuit indication without auxiliary contacts. NH2 construction size ensures compatibility with standardized fuse holders and base systems. The over-temperature withstand capability (95% relative humidity at 50°C) makes it suitable for challenging cabinet conditions without derating.
