Description
Part of the QP series, the Siemens Q220AFCH is a 2-pole combination arc fault circuit breaker engineered for residential systems. Rated for 20 amps at 120/240VAC, it provides comprehensive protection against series and parallel arcing conditions. This plug-on breaker installs into Siemens load centers and utilizes a pigtail neutral. It replaces the earlier Q220AFH model. With an upgraded 22kAIC rating, it safely handles higher fault currents and features an LED trip indicator for diagnostics.Specifications

Product FAQs
6 answersWhich load centers are compatible with the Siemens Q220AFCH?
This breaker is designed for use in Siemens EQ, Ultimate, PL, and ES series load centers that accept standard QP type breakers.
What is the difference between the Siemens Q220AFC and Q220AFCH?
The H in Q220AFCH indicates a higher interrupting rating of 22kAIC, whereas the standard Q220AFC has a 10kAIC rating. Both are 2-pole combination arc fault breakers.
Can the Q220AFCH be used for multi-wire branch circuits?
Yes, Siemens 2-pole AFCI breakers are suitable for multi-wire branch circuits (MWBC) where two 120V circuits share a single neutral conductor.
How is the pigtail neutral connected on this breaker?
The coiled white pigtail wire must be connected directly to the neutral bus bar in the panel. The circuit neutral wire connects directly to the breaker terminal.
What does Combination Arc Fault protection cover?
A combination type AFCI detects and mitigates both parallel arcing (line-to-line, line-to-ground, or line-to-neutral) and series arcing (such as a loose connection within a single wire path).
Does the Q220AFCH replace older Siemens 2-pole AFCI models?
Yes, it replaces the older Q220AFH branch-feeder AFCI models. The Q220AFCH upgrades the circuit to the modern Combination AFCI standard required by recent National Electrical Code updates.
