Fuses are electrical protective devices. They are made of a thermoplastic shell and a fusible link in Zinc (Zn) or Copper (Cu) alloy. MTA’s fuses are developed according to ISO standards, and their range covers blade and bolt down types.

We offer high quality standard and custom made fuseboxes in materials depending on your application, typically PA6 and PBT. The bolts are made in stainless steel for high torque tensioning. The fuseboxes can be delivered pre-assembled with fuses and conductor rails for your convenience

Of course, we offer fusehholders and housings as well.
