N-type DO Fuse Bases
Compact, high performance N-type fuse bases for fuses up to 63A are manufactured and supplied by Arco Electrical Industries. All fuse bases are manufactured to VDE 0636 and IEC 269 standards.
Primarily used to protect cables and lines, N-type DO fuse bases cover the whole-range of safeguards against overloading and short-circuit current.
Each DO-type fuse consists of a fuse base, a contact-guard cover, a guage-piece to ensure the non-interchangeability of the rated current, a DO-type fuse link and a fuse carrier to operate the fuse link.
DO-type fuses are designed for rated voltages of 380V-250V in accordance with VDE regulations, as well as for 415V - according to IEC standards.
