This advisory is to alert you to a potential safety issue with the product listed below. In extreme situations, this issue could lead to property loss or serious personal injury. The Siemens Quality Program requires continuous monitoring of the product performance. This process includes third party certifications, as well as tests and procedures specific to Siemens. We have identified a potential safety issue with 15 through 50 amp circuit breakers.


The products at issue are Siemens and Murray one inch plug-in circuit breakers, single and double pole, 15 through 50 amps, covering the 13 breaker catalog numbers and 10 enclosures (load center and meter combos) which contain these breakers. These Siemens and Murray circuit breakers, with a June 23 and June 28, 2010, may have a non-conforming "spring clip" plug-in assembly that breaks or fails to provide sufficient force to maintain a proper electrical connection in the panelboard.  Over time, this condition could lead to excessive temperature, arcing or thermal damage at the connection point, and potential damage to the panelboard’s electrical insulation. Such activity may, in extreme situations, lead to fire, property damage, or personal injury.

Immediate Safety Actions Required:
