ABSTRACT:
An apparatus for retaining a movable contact in a circuit interrupter includes a movable element that is displaced by gas pressure within the interrupter housing resulting from arcs generated during initial displacement of the movable element. The movable element may be a spanner extending between two stationary contacts. The apparatus may be configured as a three phase interrupter in which a single carrier or retainer is common to three power phase sections, and is displaced by interruption of a current carrying path for any one power phase section. The retainer may include a retaining pin which extends through the movable element. The movable element is biased into a conducting position and a head of the retaining pin contacts the movable element to hold it in a non-conducting position following a trip event.
