Mersen A15QS Amp-Trap High Speed Fuses | 150V Protection

In semiconductor protection, space-saving design cannot compromise on clearing performance. The Mersen A15QS Amp-Trap® Form 101 series is engineered to provide precise, fast-acting protection for diodes and heavy-duty devices like electrochemical rectifiers. Rated for 150VAC/DC, these fuses offer exceptionally low I²t characteristics, critical for safeguarding sensitive components during high-magnitude short circuit events.

Product Overview

The A15QS product line is distinguished by its compact footprint and versatile mounting options. With a current range spanning from 1A to 6000A, it serves as a universal solution for semiconductor applications with severe space limitations. Whether utilizing the midget-dimension ferrules for lower current levels or the "hockey puck" bolt-in designs for industrial power distribution, the A15QS ensures controlled arc voltage and minimized energy let-through.

Typical Applications

• Protection of heavy-duty semiconductor devices
• Electrochemical rectifiers and industrial power supplies
• DC common bus systems and battery chargers
• Variable speed drives and UPS systems
