Overview

The Mersen Protistor® fuse-link, SKU B075763, is a high-speed, square-body fuse designed for critical semiconductor protection in DC applications. This fuse-link operates at 4000VDC and is rated for 80A, adhering to the gR class as defined by IEC 60269-4. It is engineered to provide protection for sensitive electronic components such as diodes, thyristors, GTOs, and IGBT devices. Key features include a low I²t value, crucial for minimizing damage during short-circuit events, and excellent cycling capability. The fuse-link incorporates a striker mechanism for clear operational indication, facilitating rapid fault identification. Its construction utilizes pure silver die-cut elements embedded in solidified sand, contributing to controlled arcing and a high interrupting rating. All contact surfaces are silver-plated, and non-magnetic hardware ensures reliable performance. The square body design offers flexibility in mounting and terminal configurations for various equipment designs. This fuse-link is specifically developed for modern DC equipment, including railway power systems and auxiliary circuits, where reliable protection is essential, even at elevated temperatures. Refer to Mersen catalog for detailed specifications and application suitability.
