Abstract
A current limiting circuit interrupter with insulating wedge characterized by a circuit interrupter structure within an insulating housing and having a mechanism for opening and closing separable contacts, the contacts being separately mounted on contact mounting arms that extend in substantially parallel spaced locations to effect current limiting relationship between the arms to cause any arc forming between the opening contacts to blow out of the contacts in a direction away from the spaced contact arms, a dielectric plate-like shutter in the plane extending between the contacts and in the direction opposite the contact arms, the shutter being movable into a gap formed between the separating contacts when the contacts separate, moving mechanism for moving the shutter when the contacts open and reset structure for retracting the shutter when the contacts close.
