A3T & A6T FAST ACTING/CLASS T

THESE SMALL DIMENSION FUSES ARE THE
RIGHT FIT... FOR A TIGHT FIT

Fast acting A3T and A6T Class T fuses combine
two highly desirable features -- high current
limitation and a small physical size. Their unique
dimensions prevent the substitution of other fuses
with lower voltage ratings or current limiting
capability. These fuses have glass melamine
bodies for superior dimensional stability and
catalog numbers stamped into the blades for
permanent identification.
