ABSTRACT:
A multi-pole group-operated switch is provided for electrical power distribution circuits. The switch is self-contained and suited for ease of use with various line spacings and arrangements of the distribution lines; e.g., side-by-side (horizontal plane), phase-over-phase, and cable drops. The switch includes a plurality of switch-pole units carried at desired spacings by a base support and drive arrangement. Each of the switch-pole units includes a housing, interrupting contacts, and disconnect contacts. The housing that encloses the interrupting contacts in movable to perform the disconnect function. The base support and drive arrangement encloses a high-speed interrupting linkage for operation of the interrupting contacts of each of the switch-pole units and carries an operating mechanism that is connected to the interrupting linkage internal to a base support member of the base support and drive arrangement. The switch also includes a disconnect linkage to move the switch-pole housings. For manual operation of the disconnect function, an operating handle is provided. The operating handle and the operating mechanism are oriented and positioned relative to the switch in various predetermined locations that are desirable for the particular mounting configuration of the switch with respect to the line layout and the equipment pole. In a preferred embodiment, the switch includes integral dead-ending connection provisions and also includes integral line- parameter sensing and power-supply provisions incorporated within one or more of the switch-pole units.
