Overview

The Mersen A1014576 Protistor® is a high-speed cylindrical fuse (10x38mm, gR class) designed for full-range protection of critical semiconductor devices. Rated at 10A and 690VAC (IEC), this fuse delivers exceptional performance in applications such as inverters, UPS systems, and variable speed drives. With a rated breaking capacity of 50 kA AC and a power dissipation of 1.9 W at rated current, it ensures reliable fault interruption while minimizing thermal stress. The gR classification meets IEC 269-4 and VDE 636-23 standards, providing fast-acting response to overcurrents and short circuits. Its low I²t value (0.17 A²s pre-arcing, 0.48 A²s clearing at 1A) protects sensitive semiconductor components from damage during fault conditions. The 10x38mm size is internationally standardized for compatibility with standard fuse holders. UL recognized (file E76491) and manufactured in the US, this fuse combines precision engineering with robust construction for demanding industrial environments.
