Products that are marked "On Order" in the "Available Quantity" column are usually not in stock. Such products are available for purchase, however, due to their limited customer base, they usually have higher minimum quantities. DACPOL offers products that are not in stock for the following reasons: DACPOL currently has a large number of electronic components in stock and adds new products every day, however, tens of thousands of additional components and their various variants are available from our suppliers. Even though it is unreasonable to have all these products in stock due to the limited sales, we believe that it is in the best interest of our customers to make them available. Our goal is to inform customers about the maximum number of products available and enable them to make decisions based on specifications, prices, availability, required minimums and our technical advice. Please note that selecting the "In Stock" checkbox may limit the display to only products available for delivery straight from the shelf.

What are fuses used for?

Fuses are intended for protecting electrical receivers from overloads and short circuits. They’re equipped with fuse elements, which are burnt after overload or short circuit in a protected circuit. All fuses are constructed similarly and consist of: fuse elements, filler, enclosure, and contacts. The Fuse element has properly shaped constrictions, shaping its time-current characteristics and is welded on the fuse’s constrictions. The Fuse element is covered with a filler extinguishing electrical arc. Filler’s function is often played by a special quartz sand. The whole construction is placed in a ceramic enclosure called corpus.

Applications of fuses:

  • protection of cables;
  • protection of electrical receivers;
  • protection of transformers;
  • protection of electrical engines;
  • protection of condensers;
  • protection of semiconductor power devices: diodes, IGBT transistors, thiristors;
  • protection of electronic devices: soft-starts, inverters, rectifier;
  • protection of SN transformers, voltage inverters and SN engines.
