Instructions for secondary terminal blocks
EATON www.eaton.com
Section 1: General Information
A maximum of 14 terminal blocks providing 56 secondary contact
points are available in one cradle on the NF Frame circuit breaker.
The RF Frame circuit breaker is available with a maximum of 24 ter-
minal blocks providing 96 secondary contact points in two individual
cradles. The number of terminal blocks mounted depends on a num-
ber of considerations, such as whether the circuit breaker is electri-
cally or manually operated and how many features are required. For
example, the shunt trip device has two leads and uses one side of a
terminal block. Other devices, such as a motor operator, has three
leads and requires two terminal blocks. Each connection point is
permanently identified. Terminal blocks can be individually mounted
and hence contact positions may be empty.
For drawout circuit breakers, secondary terminal blocks (Figure 1) are
mounted onto an insulated support frame on the top front portion of
the drawout cassette.
Figure 1. Drawout Terminal Block.
For fixed-mounted circuit breakers, secondary terminal blocks
(Figure 2) mount onto an insulated support frame.
Figure 2. Fixed Terminal Block.
Electrical accessory leads are tagged with numbers associated with
the applicable connection diagram. Leads are also supplied with
keyed secondary connector plugs to ensure proper connections
(Figure 3).
Figure 3. Leads and Connectors (Drawout Configuration Shown).
Secondary connections are made by plugging the connector plugs
into the appropriate location. A connector plug already connected
can be removed by squeezing two release tabs together with small
needle nose pliers and pulling out (Figure 4).
Figure 4. Connector Plug Removal.
Customer wiring is done using tension clamp terminations.
Refer to manuals MN013001EN (12m x 16 / Type NF Frame)
or MN013002EN (12m x 40 / Type RF Frame) for an applicable
connection diagrams, other specific wiring, and additional
secondary contact information for all circuit breakers.

Section 2: Installation and Removal of Fixed
Terminal Blocks
ote:N Many illustrations use the NF Frame circuit breaker for illustrative pur-
poses only. The RF Frame circuit breaker is handled in a similar fashion.
Proceed with the following eight steps.
Step 1: Remove the four screws holding the front cover in
place (two on each side of the cover).
Figure 5. Step 1.
Step 2: Remove the front cover. Pull down on the charging
handle to simplify removal.
Figure 6. Step 2.
Step 3: Become familiar with the fixed terminal block mount-
ing plate where secondary connections are made.
ote:N Secondary connection points have numerical and descriptive laser-
etched identifications.
Figure 7. Step 3.
Step 4: Plug the accessory connector plug into fixed second-
ary terminal block.
Figure 8. Step 4.
Step 5: Identify correct mounting location on fixed terminal
block mounting plate for mounting fixed secondary terminal
block. First insert the bottom end of the fixed secondary ter-
minal block into the proper location on the mounting plate.
Figure 9. Step 5.
Step 6: Rotate the top end of the terminal block in until it
engages the appropriate flexible mounting tab at the top of
the mounting plate with a clicking sound.

Figure 10. Step 6.
Step 7: To remove a fixed secondary terminal block, lift up
on the small flexible mounting tab at the top of fixed terminal
block mounting plate, and rotate the terminal block out in the
opposite direction shown in Step 6.
IMPORTANT
KEEP IN MIND THAT TO REMOVE AN ACCESSORY PLUG ON A FIXED
CIRCUIT BREAKER, THE APPROPRIATE FIXED SECONDARY TERMINAL
BLOCK MUST FIRST BE REMOVED. ONCE THE TERMINAL BLOCK IS
REMOVED, THE ACCESSORY CONNECTOR PLUG CAN BE UNPLUGGED
FROM THE BOTTOM OF THE TERMINAL BLOCK. REFER TO FIGURE 4 IN
SECTION 1 FOR ASSISTANCE WITH THE REMOVAL.
Step 8: Once all terminal blocks are securely mounted, replace
the front cover and secure it in place with the four mounting
screws previously removed in Step 1.
Section 3: Installation and Removal of
Drawout Terminal Blocks
IMPORTANT
KEEP IN MIND THAT THE SECONDARY TERMINAL BLOCKS ASSOCI-
ATED WITH DRAWOUT CIRCUIT BREAKERS ARE MOUNTED ON THE
BREAKER’S DRAWOUT CASSETTE (FIGURE 11). ACCESSORY SECOND-
ARY PLUGS PLUG INTO A SECONDARY PLUG HOUSING MOUNTED
ON THE TOP FRONT OF THE CIRCUIT BREAKER (FIGURE 12). AS SUCH,
SECONDARY CONNECTIONS ARE AUTOMATICALLY MADE OR DIS-
CONNECTED DURING THE LEVERING (RACKING) PROCESS AS THE
SECONDARY PLUG HOUSING ON THE BREAKER ENGAGES OR DIS-
ENGAGES THE SECONDARY TERMINAL BLOCKS MOUNTED ON THE
DRAWOUT CASSETTE. FOR THIS REASON, ACCESSORY SECONDARY
PLUGS DO NOT HAVE TO BE UNPLUGGED TO ADD OR REMOVE TER-
MINAL BLOCKS. REFER TO FIGURES 3 AND 4 OF SECTION 1 AND THE
ASSOCIATED COPY FOR ASSISTANCE WITH CONNECTING OR DISCON-
NECTING ACCESSORY SECONDARY PLUGS.
ote:N Many illustrations use the NF Frame cassette for illustrative purposes
only. The RF Frame cassette is handled in a similar fashion.

Figure 12. Secondary Plug Engaging Plug Housing.
Proceed with the following 12 steps.
Step 1: Become familiar with the drawout terminal block
(Figure 1 of Section 1) and the terminal block mounting
bracket.
ote:N The terminal block mounting locations have numerical and descriptive
laser-etched identifications (Figure 14).
Drawout terminal block brackets are supplied as part of the
cassette and also have etched numerical identifications.
All of these identifications match the identifications on the
breaker’s secondary plug housing to ensure accurate terminal
block placement.
In addition, a terminal block alignment bracket is assembled
to provide proper alignment and separation of each individual
terminal block during the levering (racking) process. Two
alignment brackets are used with the RF Frame cassette
since two cradles are required to accommodate the addi-
tional terminal blocks. The bracket’s separation teeth ensure
this alignment and separation (Figure 13). Terminal block align-
ment brackets must be removed to add or remove terminal
blocks.

Step 2: To remove, grasp the terminal block alignment
bracket on each side and gently pull away from the terminal
blocks.
Figure 15. Step 2.
Step 3: Slide the alignment bracket out from between any
mounted terminal blocks, and put it aside for re-installment
after new terminal blocks are connected to the mounting
bracket.

Step 4: Connect the bottom part of the terminal block to
the lower part of the mounting bracket. Ensure the terminal
block is positioned accurately.
Figure 17. Step 4.
Step 5: Snap the top part of the terminal block onto the
upper part of the mounting bracket. Ensure the terminal
block is still positioned accurately and securely.
Figure 18. Step 5.

Step 6: Repeat Steps 4 and 5 until all terminal blocks are
mounted, and check to ensure they are positioned in the cor-
rect locations. A small number terminal blocks would look as
shown.
Figure 19. Step 6.
Step 7: Carefully put the terminal block alignment bracket
back into position by sliding it back into the mounted terminal
blocks.
Figure 20. Step 7.
Step 8: Push the terminal block alignment bracket over
the posts located on the terminal block mounting bracket.
Ensure the alignment bracket is fully seated.
Figure 21. Step 8.
Step 9: Once the terminal block alignment bracket is in place,
inspect it from the bottom to ensure that the teeth on the
bracket separate each individual terminal block. Only one
installed terminal block only should be visible between two
teeth when the alignment bracket is properly positioned.
Figure 22. Step 9.
Step 10: To remove already mounted terminal blocks, first
remove the terminal block alignment bracket by performing
Steps 2 and 3 in this section.
Step 11: Remove any terminal block by inserting a small
screwdriver under the mounting plate retainment tab at the
top front of the terminal block as shown, and gently pry
down to release and remove the block from the mounting
bracket.
Step 11. Step 12: After all terminal blocks to be removed are
removed, perform Steps 7, 8, and 9 in this section to com-
plete the removal process.
