Siemens Arc Fault Circuit Interrupters
What are are Arc Faults?
The UL Standard for AFCIs (UL 1699) defines an arcing fault as an unintentional arcing condition in a circuit. Arcing creates high intensity heating at the point of the arc resulting in burning particles that may over time ignite surrounding material, such as wood framing or insulation. The temperatures of these arcs can exceed 10,000 degrees Fahrenheit. Repeated arcing can create carbon paths that are the foundation for continued arcing, generating even higher temperatures.
Typical Causes of Arc Faults
Worn electrical insulation
Wires or cords in contact with vibrating metal
Overheated or stressed electrical cords and wires
Misapplied or damaged electrical appliances
Siemens introduces the new simple, spacious and secure Plug-on neutral load centers with electronic breakers. The Siemens Plug-On Neutral Combination Type AFCI breaker detects arcing faults (an unintentional arcing condition in a circuit) that standard circuit breakers are unable to detect. This AFCI circuit breaker is the same, reliable design, without the pigtail, specifically design for the Plug-On Neutral Load Centers. These breakers now only have a single load lug. The branch neutral conductor is returned to the neutral terminal bar for simpler and quicker wiring.
