Why Choose the Mersen NH0UD69V32PV Protistor® Semiconductor Fuse?
The Mersen NH0UD69V32PV is a high-speed NH size 0 semiconductor fuse engineered to protect sensitive power semiconductor devices against damaging short-circuit currents. As part of the trusted Mersen Protistor® range, it provides rapid fault interruption and exceptional current-limiting performance for industrial drives, converters, rectifiers, UPS systems and other power electronic equipment.
Featuring an aR operating characteristic, the NH0UD69V32PV is specifically designed for semiconductor short-circuit protection. Manufactured using pure silver fuse elements embedded in solidified silica sand with silver-plated contact surfaces, it delivers low let-through energy, high interrupting capacity and dependable long-term performance. The fuse is also equipped with a double visual indicator for rapid identification after operation.
With a 32 A rated current, 690 V AC (IEC) / 700 V AC (UL) voltage rating and a robust NH size 0 square-body design, the NH0UD69V32PV is ideal for protecting IGBTs, thyristors, GTOs and power diodes in demanding industrial applications. It is designed for installation in compatible NH fuse bases and fuse-switch disconnectors conforming to DIN standards.
