## Description

Siemens introduces the new simple, spacious and secure Plug-on neutral load centers with electronic breakers. The dual-function circuit breaker combines class A 5mA GFCI and combination type AFCI, protecting against both arc faults and ground faults. This, along with the new self-test feature, makes it the first in class in electrical safety for homeowners. 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. 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.

Review: These are easy to install if you have a compatible plug on neutral box. Fits tight. Works perfect. No more searching the wall for the GFCI and looking for the breaker at the same time, it’s always all in once place in the box. Used 4 of these in my garage for 3 years so far and going strong. GFCI tester proves good functionality.
Review: Just as described, fsst shipping and excellent price
