Abstract:

Bulk and accessibility problems in a motor control unit for installation in a motor control center are eliminated in a unit having a housing (10) in the shape of a rectangular solid and provided with a top wall (14), a bottom wall (16) spaced from the top wall (14), a rear wall (12) and a front (20). A plurality of motor control instrumentalities (24), (26), (36) are located within the housing (10) and are mounted to at least one of the walls (12), (14), (16) in close proximity to the rear wall (12). A side wall (22) is located to one side of the top, bottom and rear walls (12), (14), (16). A pivot (78) mounts the side wall (22) for pivotal movement about an axis generally parallel and in proximity to the rear wall (12). A disconnect switch (104) is carried by the side wall (22) to be disposed in the housing (10) in one position of movement of the side wall (22) relative thereto and a partial front wall (80) is provided for the housing and carried by the side wall (22). An actuator (82) for the disconnect switch is mounted on the partial front wall and a linkage (90), (92), (94), (96), is mounted on the side wall (22) and interconnects the actuator (82) and the disconnect switch (104).
