ABSTRACT:
In order to eliminate contact bounce and electrodynamic repulsive forces upon closure in a standard high rating circuit breaker device when a fault exists, an armature is disposed on the movable contact assembly and an iron core pole is disposed adjacent the stationary contacts, the normal current path providing a partial turn about the core. As current passes through the contact assembly the resulting magnetic field attracts the armature and hence the movable contact assembly toward the stationary contacts.
