A method of heat treatment process for distortion control of complex sheet metal component

Disclosed is a Draw out type of circuit breaker supported on the rail assembly or any equivalent draw-out assembly, which may be an integral part of the Cradle assembly. The Cradle assembly (11) consists of the base plate (12), Racking assembly (13), side plates (14) for guiding breaker and rail assembly (15). Racking operation may be accomplished by the racking assembly mounted on the base plate (12). The rotation of detachable crank causes breaker to move in or out of the cradle depending upon the direction of rotation of crank i.e. whether it is a rack-in (clockwise) or rack-out (counter-clockwise) operation. When the racking handle is rotated in the clockwise direction, the breaker is racked in (Disconnected - Test - Connected) and on the other hand, when rotated in counter clock wise direction, the breaker is racked-out (Connected - Test - Disconnected).
