A draw out interlock mechanism comprises a draw out trip arm pivotally attached in a draw out circuit breaker and an interlock activating assembly attached to a the draw out circuit breaker. The draw out trip arm comprises a first extension on a first end and a second extension on a second end. The first extension is positioned to interact with a trip latch of the operating mechanism. The interlock activating assembly comprises an extended arm and a camming arm, which are pivotally attached to a pin supported by a mounting bracket attached to the draw out circuit breaker. The extended arm extends through an aperture in the draw out circuit breaker with an end thereof proximate to the second extension of the draw out trip arm. The camming arm is adapted to interact with a camming surface attached to the draw out circuit breaker compartment such that when the draw out circuit breaker is inserted into the compartment, the camming arm and the extended arm rotate independently clockwise, the extended arm interacting with the draw out trip arm causing the draw out trip arm to rotate in counterclockwise, which in turn causes the first extension of the draw out trip arm to interact with the trip latch causing the draw out circuit breaker to trip, opening the contacts in the draw out circuit breaker.
