The Mersen NH2UD69V200PV is a premium NH Size 2 square body high-speed semiconductor protection fuse from the trusted Mersen Protistor® series. Specifically engineered to protect sensitive power electronic equipment, this ultra-fast aR fuse provides exceptional protection for IGBTs, thyristors, GTOs, diodes and other semiconductor devices against damaging short-circuit currents while delivering outstanding current-limiting performance.
Manufactured using pure silver fuse elements embedded in solidified silica sand, the NH2UD69V200PV offers low let-through energy (I²t), a high breaking capacity and silver-plated blade contacts for dependable long-term operation. The NH Size 2 design conforms to DIN 43620, allowing installation in standard NH modular fuse holders and fuse switch disconnectors used worldwide.
With a 200 A rated current and 690 V AC (IEC) / 700 V AC (UL) voltage rating, this fuse is ideal for industrial drives, UPS systems, converters, renewable energy equipment and other demanding power conversion applications requiring rapid semiconductor protection.
The Mersen NH2UD69V200PV rapidly interrupts fault currents before they can damage expensive semiconductor components. Its low energy let-through characteristics improve equipment reliability, reduce maintenance costs and minimise costly production downtime in demanding industrial applications.
Protistor® NH fuses are trusted worldwide in power conversion systems where dependable protection of semiconductor devices is essential, including industrial automation, renewable energy and heavy-duty motor control equipment.
