The Mersen X076426 (Catalogue No. DN00UC10C160L) is a Protistor® high speed square body semiconductor fuse engineered to provide ultra-fast protection for sensitive power electronic equipment. Designed specifically for safeguarding IGBTs, thyristors, diodes and rectifier assemblies, it delivers exceptional current limitation and low energy let-through to minimise semiconductor damage during short-circuit conditions.
Manufactured in the compact NH Size 00 format with DIN 80 blade terminals, the X076426 incorporates an integrated striker (trip indicator) for use with compatible microswitch accessories. Silver-plated contacts, pure silver fuse elements and solidified silica sand construction provide excellent interrupting performance and long-term reliability in demanding industrial environments.
With a 160 A current rating, 1000 V AC IEC voltage rating and an aR operating characteristic, the X076426 is ideally suited for variable frequency drives, industrial inverters, UPS systems, renewable energy converters and other power electronic equipment requiring reliable semiconductor protection.
The Mersen X076426 has been developed to protect expensive power semiconductors from destructive short-circuit currents. Its low I²t characteristics reduce thermal and mechanical stress on IGBTs, thyristors and diodes, helping maximise equipment reliability while reducing maintenance costs and downtime.
Its aR operating characteristic provides partial-range protection specifically for semiconductor devices and should be used alongside suitable overload protection where required by the equipment design.
