Definitions

  • the arc will be formed between the rings of the pair of contact. Especially, during the high current arcing phase, and at large contacts gap-distance the constricted arc roots are attached to the external edges of the contact pieces. With this scenario, from certain contacts separation distance, especially greater than 8mm, the arc undergoes an outward bending or turns into arc jet mode. This arc jet mode is also observed with other standard spiral-type contacts. Hence, the contacts-shield distance is usually increased to avoid the direct arc-shield interaction. Ideally, the arc should rotate and remain between the rings of the cup-shaped contact pieces to avoid its eventual interaction with the shield and to prevent the metal melt diffusion to the lateral slits of the cup- shaped contact.
  • each cup-shaped contact part is provided with a vertical inward bending towards the contact ring, wherein the outer diameter of the bottom section of the cup-shaped contact part is larger than the outer diameter of the rim section, in order to alter the Lorentz force to a respective inward direction.
