The Mersen NH00UD69V40PV (Item Number L320147) is a premium Protistor® NH Size 00 high-speed semiconductor fuse engineered to provide ultra-fast short-circuit protection for modern power electronic equipment. Rated at 40 A with a voltage rating of 690 V AC (IEC) / 700 V AC (UL), it safeguards sensitive semiconductor devices including IGBTs, thyristors, GTOs and diodes from damaging fault currents.
Featuring an aR utilisation category, the NH00UD69V40PV is specifically designed for semiconductor short-circuit protection. Constructed using precision die-cut pure silver fuse elements embedded in solidified silica sand, it delivers exceptionally low let-through energy, excellent current limitation and high interrupting capacity for demanding industrial applications.
Manufactured to DIN NH standards with plain silver-plated blade contacts and a double visual indicator, this NH Size 00 fuse integrates seamlessly into NH modular fuse holders and switch disconnectors used in industrial drives, UPS systems, renewable energy installations and power conversion equipment.
Protistor® aR semiconductor fuses are specifically engineered to interrupt high fault currents before sensitive semiconductor devices can be damaged. Their ultra-fast operating characteristics minimise thermal stress, improve equipment reliability and help reduce costly downtime in industrial power electronic systems.
The NH00UD69V40PV is fully compatible with NH modular fuse holders and fuse switch disconnectors manufactured to DIN standards. Its compact NH Size 00 design and double indicator allow simple installation and rapid maintenance in industrial applications.
