Customers should refer to the wiring diagram on their specific load center for compatible accessories and breakers.
Feed two circuits from one position, offered in both plug-on and pigtail options. These breakers provide flexibility where traditional breakers cannot. You’ll minimize the need for sub-feeding panels reducing both space & installation time. Increase safety with our trusted indicator flags showing when load wires are correctly inserted.

Our AFCI, GFCI, and Dual-Function Breakers allow you to install 1 device rather than 2 - saving space in a load center. This breaker combines class A 5mA GFCI and combination type AFCIs, protecting against both arc and ground faults. This, along with the new self-test feature, makes it the “first in class” breaker for electrical safety.

Siemens residential thermal magnetic breakers save space in a load center with easy, plug-in connections and help reduce your wiring time with our INSTA-WIRE ™ feature.

Don’t lose space in a load center while protecting your whole house! Did you know that for cost and space reasons, many buildings only include one surge protection device (SPD) located at the main incoming load center and do not cascade SPDs throughout the building? Siemens new BoltShield SPDs do offer cascading – where multiple QSPDs can be stacked in a single load center giving you a vast degree of protection for your entire home. Gain a smaller footprint with BoltShield QSPD – built with a 2-inch-wide plug-on design, you get (2) 1 pole circuits.
