KEY FEATURES & BENEFITS

Fast-acting A3T 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.

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
