£50.57
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.
The Mersen NH00UD69V200PV is engineered to interrupt fault currents before they can damage expensive semiconductor components. Its low energy let-through performance and rapid fault clearing improve equipment reliability while reducing maintenance costs and production downtime.
Its standard NH Size 00 construction enables straightforward installation into compatible NH fuse holders and switch disconnectors, making it a popular choice for industrial automation, renewable energy and power conversion applications.
