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.
Features/Benefits:
•
•
•
•
Extremely current-limiting for low peak let-thru current
Unique dimensions prevent replacement by other fuse classes
Blade-stamped catalog numbers for permanent identification
Small physical size for greater design flexibility
