摘要： The present invention consists in a circuit breaker wherein a pair of rigid conductors which are disposed therein and at least one of which has a movable portion that separates a pair of contacts on the basis of the electromagnetic force of an excess current flowing through the contacts adapted to come into and out of contact with and from each other, are provided with arc shields in a manner to surround the contacts, thereby to bring forth the effects of increasing the arc voltage of an electric arc struck across the contacts and raising the separating speed of the contacts.

摘要： A circuit breaker having means for quickly opening a pair of contacts, a U-shaped flux board which surrounds the conductors that have contacts attached to the end portions thereof, so that the electromagnetic repulsive force produced by the electric current that flows through the opposing conductors in opposite directions relative to each other, will be added to the operation of the contact-opening means. The circuit breaker of the invention is further equipped with arc shielding members surrounding the contacts, so that the arc established across the contacts will not stretch to the conductors in the vicinities of the contacts, and so that the arcing voltage is greatly increased.

摘要： The present invention relates to a circuit breaker comprising a pair of contactors each comprising a rigid conductor with a contact secured thereon, wherein at least one of the contactors is also provided with an electrically conductive projection secured on the rigid conductor in proximity to the contact, the contact and the projection having their peripheries surrounded by a high resistivity arc shield of a resistivity higher than the rigid conductors. An arc extinguishing plate assembly is also provided to cool and extinguish an arc drawn across the gap between the contacts. With this arrangement, the arc is confined and has its voltage raised by the effects of the arc shield, and the size of the foot of the arc is limited such that it does not spread to the surface of the conductor in the vicinity of the contact. Further, the foot of the arc is caused to shift from the contact to the projection, substantially preventing wear of the contact and further extending the length of the arc to more effectively cool and extinguish the arc.
