A50QS 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 protection features – lower I2t 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 dynamic solid state equipment such as motor drives, inverters, UPS, etc.
Lowest I2t for greatest protection of semiconductor circuits
Low watts loss for cooler operation
Superior cycling ability gives an equipment design advantage
State-of-the-art protection for 500V equipment
Ultra compact sizes allow down-sizing of existing equipment
