Abstract: A commutating circuit breaker that progressively inserts increasing resistance into a circuit via physical motion of a shuttle that is linked into the circuit by at least one set of sliding electrical contacts on the shuttle that connect the power through the moving shuttle to a sequence of different resistive paths with increasing resistance; the motion of the shuttle can be either linear or rotary. At no point are the sliding stator electrodes separated from the matching stationary stator electrodes so as to generate a powerful arc, which minimizes damage to the sliding stator electrodes. Instead, the current is commutated from one resistive path to the next with small enough changes in resistance at each step that arcing is suppressed. The variable resistance can either be within the moving shuttle, or the shuttle can comprise a commutating shuttle that moves the current over a series of stationary resistors.
