• Some installations use multiple power sources that are required to supply
energy simultaneously, alternately, or, in a specified sequence.
EntelliGuard G Circuit Breakers can be used to interconnect these sources
and be electrically and mechanically interlocked to provide the necessary
transition and protection. Mechanical Interlocks are available for fixed and

draw out circuit breakers. The interlocks enable directly interlocking

breakers that are mounted side by side or in vertical stacks. The interlocks
Hi-Fi = High Fidelity
SD = Secondary Disconnect
**In order to output the RTC contact output via Trip Unit (options 3, F, J,
consist of two components: (A) The factory-installed bracket fitted to the
breaker (fixed breakers) or the cassette (drawout breakers), and (B) The
field-installable interconnecting cables available in lengths of 1.0, 1.6, 2.0,
2.5, 3.0, 3.5 and 4.0m (ordered separately). Refer to Section 4 for
interlocking schemes.
• Contact factory for availability.
M) a communications package must be selected in Advanced Features
(Code 19/Step 16); this requires Secondary Disconnect Block B.
**If a UL or ANSI Switch is selected, the (Hi-Fi Through Trip Unit) is not
valid (Options 3, F, J, M).
**RTC Through the Trip Unit is not a valid option for Switches. Bell Alarm
Contact with Lockout comes with the Trip Unit set to Manual LO
Enabled.
• The term “Hi-Fi” refers to gold-plated contacts use for signal level
outputs (10mA minimum - 100mA maximum, 5-30Vdc, 125vac).
• Option "B", “I”, “2”, “3”, “K”, “L”, “M”, and “X” are the only valid options
when a Switch is selected in Digit 2.

• This option provides factory installed interlocking devices for
installation between separate circuit breakers (baseplates and
mechanism). This safeguard ensures that a circuit breaker cannot be
closed unless the dedicated key has been inserted and secured
within the lock.
• If selecting a Draw Out Breaker (Digit 6), consider putting the Key
Interlock on the Cassette versus the breaker. This enables the ability
to swap breakers without having to change the key interlocks.
• Locks and Keys are NOT Supplied by GE.
