摘要： Electrical switchgear comprises a fixed input contact (59), a fixed output contact (85) and a fixed auxiliary contact (82). A movable contact (83) is movable from a closed position wherein it connects the input and output contacts (59, 85) into an open position wherein it connects the auxiliary and output contacts (82, 85). An arcing electrode (76) having a substantially circular periphery is connected to the input contact (85), and is radially surounded by a coil (78) having a conductive ring (77) on its inner circumference. The ring is radially spaced from the arcing electrode (76) and the parts are arranged so that when the movable contact opens an arc is formed between the moveble contact (83) and the arcing electrode (76), the arc commutates to a location between the arcing electrode (76) and the conductive ring (77) and arcing current flows through the coil and produces a magnetic field which causes the arc to rotate and become extinguished. The arcing electrode (76) is permanently electrically connected to the input contact (59), and the coil winding is electrically connected between the conductive ring (77) and the auxiliary contact (82).

摘要： A fuse for an alternating current ppower circuit. The fuse comprises an input terminal (4), a first contact (5) electrically connected to the input terminal, an output terminal (9) and a second contact (8) electrically connected to the output terminal. A fusible element (11) electrically connects the first and second contacts and completes a normal electrical path between the input and output terminals. An arcing contact (6) is positioned in relation to the first contact (5) so as to form a potential arc path between the first contact and the arcing contact, along which path an arc will become established after the fusible element breaks in response to fault current. The arcing contact (6) is electrically connected to a third terminal (41) and is electrically isolated from the output terminal (9).
The fuse can be used in a single phase circuit to reduce let-through energy to a load under fault conditions, or in each phase of a multi-phase circuit to break the supply to all phases in response to a fault on any one phase.摘要翻译： 用于交流ppower电路的保险丝。 熔丝包括输入端子（4），电连接到输入端子的第一触点（5），与输出端子电连接的输出端子（9）和第二触点（8）。 可熔元件（11）电连接第一和第二触点，并且在输入和输出端子之间完成正常的电路径。 电弧触点（6）相对于第一触点（5）定位，以在第一触点和电弧触点之间形成电弧路径，沿着该路径，在可熔元件响应于 故障电流。 电弧触点（6）电连接到第三端子（41）并且与输出端子（9）电隔离。 保险丝可以用于单相电路，以在故障条件下或在多相电路的每个相位中减少通过能量，以便响应于任何一相上的故障来断开对所有相的供电。
