Why Choose the Mersen D075535 Protistor® High-Speed Semiconductor Fuse?
The Mersen D075535, catalogue reference DN00UD10C100L, is a Protistor® NH Size 00 high-speed semiconductor fuse engineered to provide ultra-fast short-circuit protection for sensitive power electronic equipment. Featuring an aR operating characteristic, it is specifically designed to protect diodes, thyristors, IGBTs and other semiconductor devices operating in demanding industrial applications.
Manufactured using precision die-cut silver fuse elements embedded in solidified silica sand within a robust ceramic body, the D075535 delivers excellent current-limiting performance with low let-through energy (I²t) and high interrupting capacity. Silver-plated contact surfaces ensure low electrical resistance, while the integrated striker mechanism enables remote fuse indication when used with a compatible microswitch.
Rated at 100 A with a 1000 V AC IEC voltage rating, this DIN 80 NH Size 00 fuse is ideal for variable frequency drives, industrial converters, UPS systems, renewable energy equipment and other power conversion applications requiring reliable semiconductor protection.
