A50QS

Semiconductor Protection Fuses

®
A15QS Amp-trap Form 101 fuses grew out of the need to improve
the overall performance of semiconductor fuses in response to new
equipment requirements. The A50QS encompasses the best
2
protection features - lower I t to provide better protection for
equipment, longer life when subjected to cyclic loading and lower
watts loss. A50QS is today's best choice for the protection of dynam-
ic solid state equipment such as motor drives, inverters, UPS, etc

Features/Benefits

• Lowest l t for greatest protection of semiconductor circuits
2
• low watt loss for cooler operation
• Superior cycling ability gives an equipment design advantage
• State of the art protection for 500 volt equipment
• ultra compact sizes allow down-sizing of existing equipment
