A70QS AMP-TRAP®–Form 101
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
HIGHLIGHTS:
700V AC/DC Rated
Very Low l2t
Low Watts Loss
Superior Cycling
Ability
APPLICATIONS:
Protection of 700V
or less motor drives,
UPS, inverters, etc.
