The EntelliGuard R retrofill circuit breakers provided as replacements for AKR 800-2000A frame circuit breakers
have a trip interlock feature which will function using the AKD-6 compartment mounted Key Interlock. A label is
provided with full instructions on how to operate the Legacy Key Interlock. It is suggested to apply the label on the
inside of the compartment door. Following is a brief summary of how the Key Interlock system is operated.
To activate the key interlock:
1)
OPEN the breaker.
2)
Rotate the screw on the lower front panel of the breaker which normally allows access to the racking
screw. This will hold the breaker trip free.

While the screw is held rotated Clockwise, the Key Interlock slide in the switchgear is pushed inward,
elevating a pin on the left side of the breaker.
4)
Turn the key to the key removal position, extending the bolt and lock the breaker in the OPEN position.
