A secondary disconnect assembly is for electrically connecting and disconnecting accessories to an electrical switching apparatus, such as a power circuit breaker. The secondary disconnect assembly includes a terminal block assembly comprising a mounting member, at least one terminal block removably mounted on the mounting member, and at least one accessory plug structured to be removably inserted into the terminal block to be electrically connected to the terminal block. The terminal block and the accessory plug each include a plurality of error-proofing features. The error-proofing features prohibit insertion of the accessory plug into the terminal block unless the accessory plug is correctly disposed in a predetermined orientation.

Electrical switching apparatus and secondary disconnect assembly with error-proofing features therefor

A secondary disconnect assembly is for an electrical switching apparatus, such as a power circuit breaker. The secondary disconnect assembly includes a terminal block mount having a number of first mounting features, at least one terminal block, and at least one accessory plug. Each terminal block includes a number of receptacles and a number of second mounting features, which cooperate with the first mounting features to properly align, mount and stabilize the terminal block on the terminal block mount. Each accessory plug includes a number of contact alignment features structured to align and guide the accessory plug into a corresponding one of the receptacles.

Electrical switching apparatus and secondary disconnect assembly with contact alignment features therefor

A secondary disconnect assembly is for an electrical switching apparatus. The secondary disconnect assembly includes a mounting member 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 an inner cradle. When the inner cradle is disposed in a first predetermined one of the positions, movement of the inner cradle is restricted with respect to the mounting member. When the inner cradle is moved toward a second predetermined one of the positions, the inner cradle moves independently with respect to the mounting member.

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

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.
