GFCI Circuit Breakers Recalled by Siemens Energy & Automation
Voluntarily recalling about 144,000 2-pole ground fault circuit interrupter (GFCI) circuit breakers, typically used with hot tubs and spas to prevent shock or electrocution. These GFCI circuit breakers could overheat and lose their ability to prevent injury or death. Siemens is not aware of any injuries involving these circuit breakers. This recall is being conducted to prevent the possibility of injury. The 2-pole GFCI circuit breakers involved in this recall carry the Siemens or Murray brand name. The face of the black plastic units have a large, white button with the word TEST molded into it.
I-T-E Circuit Breaker Box Inspection Program Announced By Siemens
Voluntarily offering free inspection and correction of certain of its I-T-E brand circuit-breaker boxes (load centers) installed between September 1986 and May 1987. Siemens is extending a program begun in November 1986 when it discovered that some of the circuit-breaker boxes were manufactured using components of an incorrect material, which could cause overheating and malfunction.
Siemens Recalls Circuit Breakers Due to Fire Hazard
Name of product: Siemens and Murray circuit breakers, load centers and meter combos. The recalled circuit breakers have a spring clip that can break during normal use, leading to a loss of force to maintain a proper electrical connection in the panelboard. This can lead to excessive temperature, arcing or thermal damage at the connection point, and damage to the panelboard’s electrical insulation and can result in a fire, property damage, or personal injury.

Consumer lost partial power to pole barn. Consumer heard electrical sparking from main fuse panel & tightened pole barn breaker, Next day all power in barn was out. Breaker was trippped & panel began to arc. Wires & breakers were burning. Fire extiguishers were used on fire.
Consumer has had to replace 3 breakers in load center due to spring clips on back of them losing connection with buss bar & arcing. Consumer stated that most frequent completely burned up stab on breaker box to point it can’t be used again.
Breaker box in trailer is sizzling & sparking.
Consumer states pole type circuit breaker was connected to air conditioner when one pole tripped. This caused an overheat/arc situation, resulting in the spring clip of one pole breaker to melt to the busbar in the panel, and damage to the outer casing of the breaker.
Consumer's wife heard buzzing, walked over to box & discovered that buzzing was coming from circuit panel. He opened panel & saw it was arcing. He turned main preaker off, pulled panel out & saw that one of breakers had melted. Panel box was ruined on right side.
When consumer tried to test circuit breaker at home in accordance with instructions on electric panel board it would not trip when test button pushed. Consumer is concerned that circuit breaker failure could lead to fire caused by arcing of electrical system.
A 43 YOM reports Circuit breakers had thermal fatigue/expansion of metal clip-to load bus & resulted in electrical arcing to center load bus; breaker failed to interrupt circuit, which resulted in electrical fire within load center. It used in heat pump system.
Circuit breakers are four years old and were installed in 2010. Consumer was attempting to power his generator during power outage & could not shut breaker off in order to supply power to his home through generator.
Siemens Series C M1020MB1100F
31 YOF had problems for year or two with mobile home breakers tripping constantly. One did not trip, arced, and melted the hot bus bar. It caused more electrical breakers to trip.
Consumer reported that GFI circuit breakers are constantly tripping in his apartment. It was determined that one of circuit breakers had burnt contacts & the stab of buss bar. Power in affected area was dropping to 70VAC & appliances don't work well with this level of voltage
The consumer stated that they noticed smoke coming from their home electrical panel. He opened tha panel and found the bottom left 2-pole 40-amp had heated up, melted, and caused other adjacent breakers to begin heating up; the bus bar got hot as a result.
Consumer reported that the bus bar of circuit-breaker box corrosion and deterioration resulting in circuit breaker arcing and service failure within consumer's home.
Consumer's electrical breaker emitted stray blue voltage. It was found to be overheating from arcing. Consumer replaced damaged breaker with another one with no problems afterwards.
44 YOM reports that he and two others in his home noticed a burning odor coming from the circuit breaker panel box when a vacuum cleaner was in use. The odor returned when a circuit breaker had been tripped. A power strip in an adjacent room had partially melted.
