CENTERLINE 2100 NEMA LVMCC 100msec Duration Rated ArcShield R Frame Inability to Turn Off Breaker on Loss of Internal Control Power Posted on January 1, 2021 by Brandy McNeil Centerline 2100 LVMCC Inability to Turn Off Breaker on Loss of Internal Control Power Product Safety Group 1201 South Second Street Milwaukee, WI USA 53204 firstname.lastname@example.org expanding human possibility™ 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 NEMA LVMCC 100msec Duration Rated ArcShield R Frame Inability to Turn Off Breaker on Loss of Internal Control Power Reference: 2021-01-001 Date: January 2021 This Product Notice informs you of a potential anomaly that exists with the CENTERLINE® 2100 NEMA LVMCC 100msec duration rated ArcShield™ R Frame. If control circuit power is lost, the panel door cannot be opened, and the internal circuit breaker cannot be operated. PRODUCT NOTICE Page 2 of 11 expanding human possibility™ – Product Identification – The affected products are CENTERLINE 2100 LVMCC catalog number 2193 with options TRUG (3000A R-frame breaker) and 112B (100ms Duration rated ArcShield). The full list of affected products by serial number is attached as appendix B. Product may be identified by the serial number listed on the product nameplate. The serial number is shown in the CATALOG NO. / SERIAL NO. field. In the example shown to the left, the serial number is 6504850087/100. This serial number matches one listed in Appendix B and is subject to this notification. – Description – A potential anomaly exists with the CENTERLINE 2100 NEMA LVMCC Duration rated ArcShield R Frame. If power is lost to the control circuit, the panel door cannot be opened, and the internal circuit breaker cannot be operated. The ArcShield R-frame 100msec duration rated LVMCC relies on push buttons to power a shunt trip and shunt close using a line powered control transformer to operate the panel door interlock. If the control circuit loses power with the circuit breaker ON, the following occurs: • The buttons on the door become inoperative. • The circuit breaker cannot be turned off. • The door interlock cannot be released, and the panel door cannot be opened. The user is unable to access manual buttons on the front of the R-frame circuit breaker with the current ArcShield design. There is no bypass built into the door. This product is the main incoming for a LVMCC lineup. The circuit breaker will remain ON continuing to power the installation. – Temporary Workarounds – ATTENTION: Only persons skilled in the maintenance of industrial control and electrical equipment should attempt to perform the following actions. Failure to follow industry standard safety procedures, including Lock-Out / Tag-Out (LOTO) and use of appropriate levels of personal protective equipment (PPE), may result in harm to personnel or loss of equipment. If this anomaly occurs and the retrofit kit has not been installed, the following workaround will allow access to the cabinet. PRODUCT NOTICE Page 3 of 11 expanding human possibility™ ATTENTION – You must remove power to the cabinet prior to performing these actions. Removing the catch angle disables the locking mechanism and can allow user contact with live circuits. 1. Disconnect power to the unit and perform Lock-Out / Tag-Out (LOTO) procedures. 2. Locate the hardware holding the catch angle to the door. Refer to the image shown at the left. 3. Grind or chisel off the catch angle hardware. This will cause the catch angle to fall into the cabinet, allowing the door to be opened. The catch angle should be reattached to the door using standard nut and bolt hardware. Make sure the catch angle is reattached prior to restoring power to the cabinet. Important – After performing the workaround actions, you must make sure all materials, including the catch angle and associated fasteners, are located and removed from the cabinet. Failure to do so may result in a short circuit when power is restored to the cabinet. – Correction – The correction requires the installation of retrofit parts. The instructions for the field retrofit are included in appendix C. Rockwell Automation will provide retrofit parts for a period of 18 months after publication of this Product Notice. Customers should contact Rockwell Automation Technical Support to request a retrofit parts. When calling Technical Support it is important to reference this Product Notice – PN 2021-01-001. – Requested Customer Action – Rockwell Automation requests you take the following actions: • Check if you have a product affected by this Product Notice.

Issue: A reset button to de-energize the R-Frame circuit breaker is missing from the door. Impact: If a fuse on the control transformer opens, the control station that energizes and de-energizes the circuit breaker will no longer function. If the control station is no longer functional, the circuit breaker can no longer be de-energized. The door lock on the circuit breaker will not release with the circuit breaker still energized. Resolution: Install a reset button in the polycarbonate window of the door. The reset button will be positioned over the OFF button of the circuit breaker. This reset button will allow the circuit breaker to be de-energized if a fuse opens on the transformer. The photo below illustrates the position of the reset button on the door. Section without the reset button installed: PRODUCT NOTICE Page 8 of 11 expanding human possibility™ Section with the reset button installed The following instructions show how to install the reset button in the window. Reset button installation steps: 1. Before working on the section to install the reset button, the control station should be used to de-energize the circuit breaker. Before performing any additional work on this MCC, remove all power from this MCC after de-energizing this circuit breaker. This allows the door to be opened and access to the window. 2. A hole for the reset button will need to be added to the window. The current design has the window being held in place by (4) pieces of hardware. The hardware should be removed so that the window can be removed for alteration. 3. Once removed, the window will need to have a 0.50” (12.7mm) hole added to the window. The hole will be located at 3.06” (77.7mm) from the left edge and 4.02” (102.1mm) from the bottom edge. The image below shows the location that the hole should be located on the window. PRODUCT NOTICE Page 9 of 11 expanding human possibility™ 4. Once the hole is added to the window, it can be re-installed on the door. The double-sided tape and the hardware used to mount the window on the door should be re-installed. When installed properly the hole will be in the bottom left quadrant of the door. Please refer to the picture at the beginning of this section for proper orientation. 5. Once the window is back in place, the reset button can be installed. The reset assembly will arrive fully assembled. The picture below shows the reset assembly and identifies the parts. The parts are (1) button screw, (2) spring, (3) bushing, (4) lock ring and (5) reset extension. PRODUCT NOTICE Page 10 of 11 expanding human possibility™ 6. To install the reset, place the bushing into the hole that was cut into the polycarbonate window until the bushing sits flush in the window. The lock ring will then be placed on the bushing from the inside side of the door until it sits flush against the polycarbonate window. If properly installed the reset bushing should be held in place. 7. Once the bushing is in place, the spring can be placed in the bushing. 8. The reset screw is then place in the bushing to hold the screw inside the bushing. 9. With the reset screw and spring being held in place, the reset extension is then screwed onto the reset screw. If properly installed, the front of the reset screw should be flush with the front of the bushing. The reset extension should be held securely onto the reset screw. Refer to the pictures below to see what the installed button should look like. View of installed reset from front side of the viewing window.
