Why Choose the Mersen NH0UD69V315PV High-Speed Semiconductor Fuse?

The Mersen NH0UD69V315PV (Item Number E320279) is a Protistor® NH Size 0 high-speed semiconductor fuse designed to provide maximum protection for modern power conversion equipment. Featuring an aR operating characteristic, it delivers ultra-fast short-circuit protection for sensitive semiconductor devices including diodes, thyristors, GTOs and IGBTs while offering outstanding current-limiting performance.

Manufactured using precision die-cut pure silver fuse elements embedded in solidified silica sand within a robust ceramic body, the NH0UD69V315PV provides exceptionally low let-through energy (I²t), high interrupting capacity and reliable operation in demanding industrial environments. Silver-plated blade contacts minimise electrical resistance, while the integrated double visual indicator enables rapid identification of an operated fuse for easier maintenance.

Rated at 315 A, with 690 V AC (IEC) and 700 V AC (UL) voltage ratings, this NH Size 0 fuse is designed for installation in DIN 43620 NH fuse holders and fuse switch disconnectors. It is ideally suited for variable speed drives, industrial converters, UPS systems, renewable energy equipment and other demanding semiconductor protection applications.
