Definitions:

 
  • R-Rating: An "R" rated fuse will melt in the range of 15 to 35 seconds at a value of current equal to 100 times the "R" number. Prior to the institution of "R" ratings, motor fuses were rated by current. The Attached chart gives the proper conversion to current standards.
  • Back-up Current Limiting: A current limiting fuse which can interrupt any current in between its rated minimum interrupting current and its rated maximum interrupting current. Back-up fuses are not intended to be used as overload devices.
