This Dual Function circuit breaker is the same, reliable design, without the pigtail, specifically designed for the Plug-On Neutral Load Centers. Simple, Spacious, Secure. 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.
