Introduction
Command Closing Coil:
Command Close coil is used to switch ON the
Power Circuit Breaker remotely. When
commanded it releases the spring charged
mechanism thus ensuring a rapid connection of
the main contacts. The Command Close coil
offers an extended functionality in addition to all
the features of the standard closing coil.
Additional connections allow it to be wired out
through the trip unit to be commanded through
the communications bus. An optional electrical
close pushbutton that fits onto the breaker front
fascia is available to command the accessory
from the breaker directly.

Use the following procedure to install the
Command Closing Coil accessory into the circuit
breaker.
1. Verify that the rating on the Command Closing
Coil identification plate matches the voltage
rating required for the application, as listed in
Table 1.
2. Turn the breaker off and discharge the closing
springs by depressing the OFF and ON buttons in
the sequence OFF-ON-OFF. Verify that the
breaker OFF-ON indicator shows OFF on a green
background and that the charge indicator shows
DISCHARGE on a white background. If installing
in a draw-out type breaker remove breaker from
adaptor (cassette) before continuing.
3. Loosen the 6 screws on front cover (fascia)
using a posidrive screw driver as shown in Fig 1.B
Rotate the charging handle down and slide the
front cover over the handle to remove the front
cover as shown in Fig. 1.C.

8. Ensure the plug is inserted properly by the
snap in the secondary disconnect.
9. Place the ferrite from the coil assembly behind
the coil. Route the wire from the close coil to the
side of the PMU base for the connection with
Electrical close switch as shown in fig.6.

Reference:
Command Closing Coil Connection Scheme:
A10 –provides constant control power to
the Command Close Coil accessory.
A9 –control power return.
A11 –Separate local command input.
Must be fed from the same source as
A10.

Reference:
Command Close Coil Serial Communications
The Command Close Coil is actuated either by applying a signal voltage to the A11 terminal via external
contact or optional breaker electrical close pushbutton, or it can be commanded through a properly
configured EntelliGuard trip unit via serial communications. Note that the Command Close Coil must be
continuously powered at A9/A10 to receive trip unit commands.
Figure 2 shows the electrical interconnection between the trip unit and the Command Close Coil accessory.
The trip unit must have an auxiliary DC supply to use serial communications functions.
To command the close coil remotely using Modbus, send a Coil ON command (Modbus Function Code 05
ON) to register 111. The command will remain in effect until it is turned OFF.
To turn off the command, send a COIL OFF command (Modbus Function Code 05 OFF) to register 111.
Note that the remote command input must be set to OFF and the local command inputs must be OFF
before the close coil can be retriggered with a new command.
Refer to DEH-4567 EntelliGuard Trip Unit Instruction for more details.
These instructions do not purport to cover all details or variations in equipment nor, to provide contingency to be met in connection
with installation, operation, or maintenance. Should further information be desired, or should particular problems arise which are not
covered sufficiently for the purchaser’s purposes, the matter should be referred to GE.
