Electrical switching apparatus and secondary disconnect assembly with cradle assembly alignment and positioning features therefor

摘要

A secondary disconnect assembly is for an electrical switching apparatus. The secondary disconnect assembly includes a terminal block assembly comprising a mounting member including a number of protrusions, and a cradle assembly coupled to the mounting member and being movable among a plurality of positions with respect to the mounting member. The cradle assembly includes a cradle housing and an inner cradle movably disposed with the cradle housing. The protrusions align and guide the inner cradle with respect to the mounting member. When the inner cradle is disposed in a first predetermined one of the positions, the number of protrusions engage and lock the inner cradle to restrict movement of the inner cradle with respect to the mounting member. When the inner cradle is moved toward a second predetermined one of the positions, the number of protrusions release the inner cradle to move independently with respect to the mounting member.
