Abstract
A power switchgear is equipped with a stationary contact and contact-maker, a movable contact and contact-maker, a commutating electrode and an arc runner. The elements are constructed and arranged such that when the contacts open, the resultant arc will be quickly driven from the contacts to the commutating electrode and arc runner, to increase the life of the contacts and shorten the arcing time.
