Why Choose the Mersen Z330026 Protistor® High-Speed Fuse?

The Mersen Z330026 (Catalogue No. DN000UB69V160V) is a Protistor® NH Size 000 high-speed semiconductor protection fuse designed to provide ultra-fast short-circuit protection for sensitive power electronic devices. Rated at 160 A and 690 V AC (IEC/UL), it protects IGBTs, thyristors, diodes and rectifier assemblies used in modern industrial power conversion equipment.

Constructed using precision die-cut silver fuse elements embedded in solidified sand, the Z330026 delivers exceptionally low let-through energy and excellent current-limiting performance. Silver-plated contact blades and non-magnetic hardware provide long-term reliability, while the integrated visual indicator enables rapid identification of a blown fuse and can operate an optional microswitch for remote indication.

Designed for compact NH Size 000 installations, the Mersen Z330026 is ideally suited to variable speed drives, UPS systems, industrial converters, renewable energy equipment and automation systems where dependable semiconductor protection is essential.
