AMP-TRAP®–Form 101
A70QS
SEMICONDUCTOR PROTECTION FUSES
A70QS Amp-trap® Semiconductor Protection fuses
were developed in response to the need for improved
overall performance of 700 volt semiconductor fuses
for new equipment requirements. A70QS fuses have
lower I2t for better protection, longer life when subjected to cyclic loading, plus lower watts loss.
A70QS is the best choice to protect dynamic solid
state equipment such as motor drives, UPS, etc.
Features / Benefits
➤ Very Low l2t for improved protection of equipment
➤ Superior cycling ability for long, reliable life on high
cyclic loading
➤ Low watts loss for cooler operation
➤ 700V AC/DC rating gives greater design versatility
➤ Ultra compact sizes allow down-sizing of existing
equipment
