1. A circuit breaker, comprising:
a spanner configured to move between a first position and a second position, wherein the first position corresponds to an input conductor being coupled to an output conductor via the spanner, and wherein the second position corresponds to the input conductor being uncoupled from the output conductor via the spanner; and
a commutation bar comprising solid-state switching circuitry, wherein the commutation bar is positioned a first distance away from the input conductor, wherein the commutation bar is configured to receive an arc current as the spanner moves from the first position to the second position, and wherein the solid-state switching circuitry is configured to turn off after the spanner moves from the first position to the second position.
