DO Fuses

Mersen’s “”D0″” fuse links (IEC 60269) are cylindrical screw-type fuses for industrial low-voltage protection (up to 500V AC/440V DC). These fuses are paired with compatible fuse holders for secure mounting.
Fuse Link Types & Sizes:
D01 – 22×58mm (smallest, low current)
D02 – 22×58mm (higher current than D01)
D03 – 22×58mm (highest current in D0 series)
D – Standard screw-in (14×51mm or 22×58mm)
DI – Intermediate size (16×60mm)
DII – 22×58mm (common industrial size)
DIII – 35×80mm (higher ratings)
DIV – 50×100mm (max current/breaking capacity)
Key Standards:
IEC 60269 (gG/gL, aM)
BS 88 (UK standards)
These fuses protect motors, transformers, and distribution systems, offering compact, screw-in safety.
