Overview

Mersen A30QS2000-128IL Amp-Trap® high-speed fuse provides critical protection for power semiconductors including diodes and SCRs in 300VAC/DC applications. Rated 2000A with 300VAC/DC voltage capability, this hockey puck-style fuse features a bolt-in mounting type (128) and integral blown-fuse indicator (IL) for immediate fault detection. The A30QS series offers low I²t for minimized component damage during short circuits and controlled arc voltage to reduce stress on circuit components during clearing. With interrupting ratings of 200kA AC and 100kA DC, this fuse is UL recognized (File E60314) and designed for heavy-duty rectifiers and power supplies operating at 300V or less. The 128 mounting style ensures compatibility with standard fuse blocks while the integral indicator provides visual confirmation of fuse operation. Manufactured in Mexico, this fuse meets North American safety standards and is distributed by Gross Automation.
