Overview

The Mersen B322369 Protistor® NH Size 0 high-speed fuse-link is engineered for semiconductor protection in power conversion equipment, offering precise and reliable overcurrent interruption. Rated at 690VAC (IEC) / 700VAC (UL) and 160A, this fuse-link is designed for NH modular systems, fuse-holders, and fuse switch disconnectors compliant with DIN 43620/00. The fuse features pure silver die-cut elements embedded in solidified sand for superior arc control, resulting in lower I²t values and a high interrupting rating of 200kA. With a power dissipation of 36W at rated current, it ensures efficient thermal management in high-performance applications. The double indicator enables visual status monitoring, and optional low-voltage trip indicators allow remote signaling via microswitches. Compatible with NH Size 0 fuse systems, this fuse-link is ideal for protecting diodes, thyristors, GTOs, and IGBT devices in industrial power electronics, motor drives, and renewable energy systems. The silver-plated contact surfaces and non-magnetic hardware enhance conductivity and durability, while the plain blade design ensures secure mounting in standard NH fuse-holders. Manufactured in the US, the B322369 meets stringent IEC and UL standards for global deployment.
