Its high interrupting rating in a compact form factor of 6 x 32mm makes it a smaller fuse option to 10.3 x 38.1mm, 500V fuses. It is an ideal circuit protection solution for high energy applications.

In addition, the 505 series with high interrupting rating at both 500VAC and 500VDC which ensures the circuit is well-protected under very high current short circuit conditions.


  • DC interrupting current
  • Provides fast response to faulty current
  • UL and CSA agency approval

  • Input of 3 phase Power Supplies
  • Uniterruptible Power Supplies (UPS)
