Product FAQs
7 answersWhat load centers are compatible with the Q220AFCN breaker?
This breaker is designed exclusively for Siemens Plug-On Neutral load centers, including the SN and PN series. It requires a panel with a built-in neutral bus bar designed to accept plug-on neutral breakers.
Can I use the Q220AFCN in an older panel that requires a neutral pigtail?
No. This model does not include a neutral pigtail wire. If your load center does not have a plug-on neutral bus, you will need the pigtail version, catalog number Q220AFC.
How does the neutral connection work on the Q220AFCN?
The breaker features a plug-on neutral design that connects directly to the neutral bus bar in a compatible Siemens load center. The branch circuit neutral lands directly on the breaker terminal, eliminating the need to route a separate pigtail wire.
Is this 2-pole AFCI breaker suitable for multi-wire branch circuits?
Yes. This 2-pole Combination AFCI allows electricians to share a neutral between two 120V circuits. It is commonly used for multi-wire branch circuits (MWBC) to save on wiring costs while maintaining arc fault protection.
What is the difference between the Q220AFCN and the Q220AFC?
The Q220AFCN is a plug-on neutral breaker for newer Siemens PON load centers. The Q220AFC is the pigtail version, which includes a coiled neutral wire for installation in standard panels.
Does this breaker include diagnostic features for troubleshooting?
Yes. Siemens AFCI breakers include LED trip indicators near the push-to-test button. These LEDs help electricians determine if a trip was caused by an arc fault or a standard overcurrent condition.
What type of arc fault protection does the Q220AFCN provide?
It is a Combination Type AFCI (CAFCI). This means it is engineered to detect both series and parallel arcing faults, providing comprehensive protection against electrical fires in residential and commercial branch circuits.
