QAS/QAL/QFS/QFL Series Quick-Action Fuses INTRODUCTION The AirpaxTM QAS, QAL, QFS, QFL product lines feature L-type terminals and carry a rated voltage of up to 600 VAC and 500 VDC, 300A max, 100K AIC. They feature a high current-limiting effect and superior quick-action fusing performance, excellent arc-suppressing performance, and reliable breaking action. Because of their low power loss, they save energy and also feature low surge voltage at the breaking point. Superior non-degradation characteristics make it ideal for motors subject to extreme load variations. Typical applications include inverters, arc welders, rectifiers, CNC equipment, battery circuits, and other protective applications.
