The device may include at least one expansion zone. The device may include at least one movable component to assist in creation of the at least one constriction zone. A method of fabrication is provided.

主权项

1. A circuit interruption device comprising:
at least one line side electrical contact and at least one respective load side electrical contact, the electrical contacts disposed within a case, the case comprising a material having a high dielectric constant, the material selected from the group consisting of acrylonitrile butadiene styrene (ABS) and fiberglass; each of the line side contacts configured for engagement with a respective load side contact, the engagement for electrically connecting an electrical supply with an electrical load; wherein the engagement comprises at least one of the line side electrical contact and the respective load side electrical contact moving through an arcing zone to make an electrical connection; wherein the arcing zone comprises at least one constriction zone adapted for limiting arcing between the respective electrical contacts; and at least one movable component configured to create the constriction zone in cooperation with the movement of the electrical contact.
