Dear Rockwell Automation Customer:
The purpose of this Product Safety Alert is to inform you of a potential product issue that
has been identified.
This Product Safety Alert explains the issue and the steps being taken to rectify the
situation.
Problem Description
Rockwell Automation has determined that a hazard may be created through the improper use and
application of the Bulletin 140M Motor Protection Circuit Breakers.
PRODUCT SAFETY ALERT
Page 2
Such a hazard may be created when a Bulletin 140M Motor Protection Circuit Breaker is
improperly adjusted beyond the end of the calibrated portion of the scale (see photo below) and
several motor start conditions are attempted in series without any time delay between motor starts.
Such simultaneous conditions may cause an internal short circuit to occur within the Bulletin
140M Motor Protection Circuit Breakers, resulting in the creation of a hazard to both personnel
and equipment.
End of calibrated portion of the scale
Un-calibrated portion of the scale,
no adjustment settings allowed

Problem Correction
·
Effective immediately, all devices listed below under “Product Identification” should have the
following field modifications performed.
o
Inspect all installed product to make sure that the devices are not adjusted beyond the end
of the calibrated portion of the adjustment scale.
o
In the event that a device is adjusted beyond the end of the calibrated portion of the
adjustment scale re-adjust the device to be within the calibrated portion of the adjustment
scale.
o
In the event that the installed and properly adjusted circuit breaker does not provide the
appropriate overload protection setting, replace the existing device with a new unit that
provides the appropriate overload current range.
o
Add an additional instruction sheet inside the carton boxes of all Bulletin 140M Motor
Protection Circuit Breakers that are in inventory.
·
If there is concern that a user or maintenance person may, in the future, set the dial beyond the
calibrated portion of the adjustment scale, then please apply a self-adhesive label near the
adjustment scale directly on the Bulletin 140M Motor Protection Circuit Breakers that are either
installed or in inventory. This label will clearly show that the device should not be set beyond the
calibrated portion of the adjustment scale. Instructions for label installation will be included in
the modification kit.
·
Rockwell Automation will provide customers with a modification kit beginning in January, 2005
(Cat. No. 140M-MK1) that includes the additional instruction sheet as well as the self-adhesive
label along with clear instructions on how to apply the label.
·
Rockwell Automation has modified all present inventories and has implemented changes to the
production of frame sizes C, D and F of the Bulletin 140M Motor Protection Circuit Breakers (as
well as all starters that use these circuit breakers) to include the above product modifications.
·
Rockwell Automation will provide customers, upon request, with Anti-Tamper Shields at no
charge. The Anti-Tamper Shields (Cat. No. 140M-C-CA) provide protection against inadvertent
adjustment of the current setting.
