Why Choose the Mersen NH000UD69V200PV High-Speed Semiconductor Fuse?
The Mersen NH000UD69V200PV (Item Number D320071) is a Protistor® NH Size 000 high-speed semiconductor fuse designed to provide ultra-fast protection for modern power electronic equipment. Featuring an aR operating characteristic, it is specifically engineered to protect sensitive semiconductor devices including diodes, thyristors, GTOs and IGBTs against damaging short-circuit currents while delivering exceptional current-limiting performance.
Constructed with precision die-cut silver fuse elements embedded in solidified silica sand within a high-strength ceramic body, the NH000UD69V200PV provides low let-through energy (I²t), high interrupting capacity and excellent thermal performance. Silver-plated blade contacts ensure low resistance connections, while the integrated double visual indicator enables quick identification of an operated fuse, reducing maintenance time.
Rated at 200 A with 690 V AC (IEC) and 700 V AC (UL), this NH Size 000 fuse is designed for installation in DIN 43620 NH modular fuse holders and fuse switch disconnectors. It is widely used in variable speed drives, UPS systems, industrial converters, motor drives and renewable energy power conversion equipment.
