Abstract
An arc spinner interrupter apparatus includes a first electrical contact assembly having a fixed contact and an arcing element. A second electrical contact assembly includes an arm selectively movable along a path into and out of engagement with the fixed contact. The arcing element extends beyond the fixed contact in a direction parallel to the path of the arm and is biased toward a position at least partially within the path of movement such that the arm impacts and engages the arcing element during movement toward the fixed contact. A mass is biased toward a position in contact with the arcing element for dampening oscillation of the arcing element in a direction transverse to the path of movement. When the arm impacts the arcing element the kinetic energy of the arcing element acting in the transverse direction is transferred from the element to the mass and oscillation of the element is reduced.
