The Mersen NH0UD69V160PV is a high-performance high-speed semiconductor fuse developed to protect sensitive power electronic devices against damaging short-circuit currents. As part of the established Mersen Protistor® NH fuse range, it combines an ultra-fast aR operating characteristic with robust industrial construction for dependable protection in demanding power conversion applications.
Designed specifically for semiconductor protection, the NH0UD69V160PV limits the thermal and electrical energy allowed to pass during a fault. This rapid response helps protect components such as IGBTs, thyristors, diodes and rectifier assemblies while reducing the risk of extensive equipment damage and unplanned downtime.
With a rated current of 160 A and a rated operating voltage of 690 V AC, the NH0UD69V160PV is suitable for industrial drives, inverters, UPS equipment and other power electronic systems. Its standard NH Size 0 format and blade contacts support secure installation in compatible NH fuse bases and industrial switchgear.
High-speed semiconductor fuses operate more rapidly than conventional industrial fuses and are designed to limit the energy passing through a circuit during a short-circuit fault. This helps prevent excessive thermal stress from damaging sensitive semiconductor components and associated power electronic assemblies.
The Mersen NH0UD69V160PV is particularly suitable for equipment in which reliable fault interruption, low let-through energy and high breaking capacity are essential. Correct fuse selection can help improve equipment availability, simplify maintenance and reduce the cost of repairing damaged power electronic components.
