PRODUCT NOTICE
Notice of Potential Product Concern
Rockwell Automation issues a Product Notice when it identifies a product(s) anomaly that may cause commercial or customer
satisfaction concerns.
CENTERLINE 2100 LVMCC Fuse Clip Screws Under Torqued
Reference: 2015-05-001
Date: May 2015
This Product Notice informs you of a potential anomaly that exists with the CENTERLINE 2100 LVMCC using a
Bulletin 1494 disconnect switch or a 140M circuit breaker with fuses. Screws used to secure 30A through 400A fuse
clips to the disconnect switch may not have been tightened to the correct torque. Under torqued connections may
result in overheating at the connection.

CENTERLINE 2100 systems using a Bulletin 140M
circuit breaker with 30A through 400A cartridge fuse
clips and shipped between January 1, 2011 and April 1,
2015, are potentially affected.
Important –Systems using a Bulletin 194R disconnect switch are not affected by this anomaly.
CENTERLINE 2100 systems using a Bulletin 194R
disconnect switch are not affected by this anomaly.
The example image to the left shows a recent Bulletin
194R style disconnect switch. This image is an
example and may not be identical to that used in your
system. Older systems may use a previous style of
Bulletin 194R disconnect switch.
–Description –
This Product Notice informs you of a potential anomaly that exists with the CENTERLINE 2100 LVMCC. Screws
used to secure 30A through 400A fuse clips to both the 1494 disconnect and the corresponding trailer fuse block or
30A through 400A fuse clips used with a 140M circuit breaker may not have been tightened to the correct torque.
Under torqued connections may result in overheating at the connection. Continued overheating may result
discoloration of or damage to the fuse clip.

PRODUCT NOTICE

On 100A through 400A fuse clip assemblies, the screws
are found under the locking clips on the fuse clip
assembly where the assembly is attached to the
disconnect switch and on the trailer fuse block. Note
there are two screws under each of the clips. The
screws may be marked with red ink.
The example images to the left show the two screws on
the disconnect side of the fuse assembly and the trailer
block side with the locking clip removed from one of the
fuse clips. There are twelve (12) total screws, six (6) on
the disconnect side and six (6) on the trailer block side.
On 30A through 60A fuse clip assemblies, the screws
are found under the fuse where the fuse clip attaches to
the disconnect switch or header fuse block and the
trailer fuse block. Note there is one screw for each of
the clips.
The example image to the left shows the screw with the
fuse removed. There are six (6) total screws, three (3)
on the disconnect or header block side and three (3) on
the trailer block side.
–Temporary Workarounds –
No workaround has been identified.

–Correction –
ATTENTION: Only skilled personnel should oversee the maintenance and servicing of motor
control centers. If power sources are connected to the motor control center, use extreme caution
when inserting or removing units. All buses and the line sides of the units are energized and
contact with these parts can cause injury or death.
Follow NFPA 70E safety guidelines when working on energized equipment.
Correction requires re-torqueing the fuse clip screws to the correct torque level. Each fuse clip assembly has a
unique torque requirement. Refer to the following table for the correct torque.
Fuse Clip Rating
Target Torque (in-lbs)
Torque Range (in-lbs)
30A
30
27 to 33
60A
30
27 to 33
100A
20
18 to 22
200A
20
18 to 22
400A
30
27 to 33
Re-torqueing requires removal of the fuses from the fuse clip assembly.
1. Shutdown and lock-out tag-out (LOTO) the LVMCC system.
2. Open the system structure containing the disconnect switch and fuse clip assemblies.
3. Remove the fuses from the fuse clip assembly.
4. Depending on the type of fuse clip assembly –
For 30A and 60A assemblies, tighten the one
screw on each fuse clip on both the
disconnect side and the trailer block side of
the fuse assembly to the proper torque as
shown in the table above. There will be three
(3) total screws on the disconnect side and
three (3) total screws on the trailer block side.

PRODUCT NOTICE

For 100A, 200A and 400A assemblies, tighten
the two screws under each fuse retaining clip
on both the disconnect side and the trailer
block side of the fuse assembly to the proper
torque as shown in the table above. There
will be a total of six (6) screws on the
disconnect side and six (6) screws on the
trailer block side.
Note –In the images to the left, only one fuse
clip assembly on the disconnect side and one
on the trailer block side have the retaining
clips removed for clarity. The screws are
located under the retaining clips. All retaining
clips must be removed to access the screws.
5. Re-install the fuses in the fuse clip assemblies.
6. Following proper electrical procedures, including LVMCC installation and start-up instructions, return power
to the LVMCC system.
During implementation of corrective action, if you observe evidence of overheating or damage to the fuse block
components or surrounding components, contact Rockwell Automation Technical Support. Be prepared to provide
your system MCC serial number and images of product overheating or damage. Reference this Product Notice PN
2015-05-001 when contacting Technical Support.
