High-speed NH Size 00 fuse with 200A rating, double visual indicators, plain blade terminals, and ceramic body for semiconductor protection in industrial power systems.
Why Choose the Mersen NH00UD69V200PV Protistor® High-Speed Fuse?
The Mersen NH00UD69V200PV is a premium square body high-speed semiconductor protection fuse from the renowned Mersen Protistor® series. Designed specifically to protect sensitive power electronic devices, this ultra-fast aR fuse safeguards IGBTs, thyristors, diodes and other semiconductor components against damaging short-circuit currents while providing exceptional current-limiting performance.
Manufactured using pure silver fuse elements embedded in high-grade silica sand, the NH00UD69V200PV delivers extremely low let-through energy (I²t), high interrupting capacity and dependable long-term operation. Silver-plated contacts and a double visual indicator further enhance reliability and maintenance efficiency in demanding industrial environments.
With a 200 A rated current and a 690 V AC IEC / 700 V AC UL voltage rating, this NH Size 00 fuse is ideally suited for industrial drives, converters, UPS systems, renewable energy installations and other power conversion equipment requiring rapid semiconductor protection.
