Medium Voltage IEEE Fuses

Back-Up R-Rated DIN Style Fuses for Motor Protection

3.3 kV DIN Mount Motor

R-Rated motor starter fuses Amp-Trap® R-Rated DIN style fuses are current limiting, high interrupting rating fuses, intended for the short circuit protection of medium voltage motors and motor controllers. This product range offers North American R-Rated performance in the IEC DIN mounting configuration of 442mm. R-Rated fuses are applied as back up fuses that have a minimum interrupting rating, and must be coordinated with overload relays in combination motor starters. Amp-Trap® R-Rated, DIN type fuses are offered in voltage ratings of 3.3KV, 5.3KV and 7.2KV in ratings from 2R to 19R. All fuses within this product group are UL component recognized.



  • Clip mount DIN 45: R-Rated fuses with North American ANSI characteristics in a standard DIN 442mm size.
  • Current-limiting for superior equipment protection.
