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

APPLICATIONS

  • Load centers
  • Panelboards
  • Switchboards
  • Circuit breakers
  • Metering centers
