Overview

The Mersen A076429 Protistor® NH 00 square body high-speed fuse-link provides ultra-fast semiconductor protection with a 1000VAC rating (IEC) and 280A continuous current. Engineered for small power conversion equipment, this aR fuse delivers exceptional I²t performance with pre-arcing values of 33180 A²s and clearing values of 150000 A²s at rated voltage. The fuse features silver-plated contact surfaces and non-magnetic hardware for optimal conductivity and durability. With a 200kA interrupting rating, it meets the demands of high-fault current applications in industrial power electronics. The striker mechanism enables remote indication via microswitch for enhanced system monitoring. Designed for DIN 80 blade compatibility, this fuse-link is ideal for protecting diodes, thyristors, and IGBT devices in converters, inverters, and motor drives. Assembly includes die-cut fuse elements embedded in solidified sand for controlled arcing and consistent performance. Weight is 0.24 kg with a power dissipation of 70W at rated current.
