Why Choose the Mersen NH1GS69V200PV High-Speed Semiconductor Fuse?
The Mersen NH1GS69V200PV (Item Number D322371) is a Protistor® NH Size 1 high-speed semiconductor fuse engineered to provide comprehensive protection for modern power electronic equipment. Featuring a gS operating characteristic, it delivers both overload and short-circuit protection for semiconductor devices including diodes, thyristors, GTOs and IGBTs, making it ideal for demanding industrial applications.
Manufactured using pure silver fuse elements embedded in solidified silica sand within a robust ceramic body, the NH1GS69V200PV provides excellent current-limiting performance, low I²t values and high interrupting capacity. Silver-plated blade contacts minimise resistance, while the integrated double visual indicator enables rapid identification of an operated fuse to simplify maintenance.
Rated at 200 A, with 690 V AC (IEC) and 700 V AC (UL) voltage ratings, this NH Size 1 fuse is designed for installation in DIN 43620 NH modular fuse holders and fuse switch disconnectors. It is ideally suited for variable speed drives, UPS systems, industrial converters, inverters and renewable energy power conversion equipment.
