The Mersen NH2GS69V200PV is a premium NH Size 2 square body high-speed semiconductor protection fuse from the trusted Mersen Protistor® series. Designed specifically for modern power conversion equipment, this gS class fuse provides comprehensive protection for semiconductors including IGBTs, thyristors, GTOs and power diodes against overloads and short-circuit faults.
Manufactured using pure silver fuse elements embedded in solidified silica sand, the NH2GS69V200PV delivers exceptionally low let-through energy (I²t), high breaking capacity and dependable long-term performance. Silver-plated contact surfaces and a double visual indicator simplify maintenance while ensuring reliable operation in demanding industrial environments.
With a 200 A rated current and 690 V AC IEC / 700 V AC UL operating voltage, this NH Size 2 fuse is ideally suited to industrial drives, UPS systems, renewable energy equipment, converters and other high-performance power electronic applications.
The Mersen NH2GS69V200PV is engineered to interrupt fault currents rapidly before they can damage valuable semiconductor devices. Its low energy let-through characteristics improve equipment reliability, reduce maintenance costs and minimise unplanned downtime in critical industrial applications.
Designed to DIN NH standards for worldwide compatibility, the Protistor® NH gS series integrates easily into modular NH fuse holders and switch disconnectors used throughout industrial automation and power conversion systems.
