Overview

The Mersen H300111 Protistor® fuse-link (SKU: H300111) is a square body high-speed fuse designed for semiconductor protection in power conversion equipment. Rated at 30A aR with 690VAC/700VAC compatibility, this fuse-link meets IEC 700VAC and UL 125A standards. It features die-cut elements embedded in solidified sand to control arcing, ensuring a lower I²t and high interrupting rating. The square body design supports multiple mounting styles, including DIN 80 blades, providing flexibility in equipment design. Silver-plated contact surfaces and non-magnetic hardware enhance reliability and performance. Optional low-voltage trip-indicators enable remote status monitoring via field-mountable microswitches. Engineered for applications requiring ultra-fast acting fuses with high interrupting capacity, the H300111 protects diodes, thyristors, IGBT, and MOSFET devices in power conversion systems.
