A newer footprint for a specific job
Siemens identifies Q220GF as the newer QPFB model used in place of earlier QF220A/QF220AP configurations. It remains a ground-fault breaker, not an AFCI device. Replacement approval still depends on the panel label and the manufacturer’s instructions for the exact equipment.
Do not select by pole count alone
Verify the QPFB family is accepted and that the circuit requires a 20A common-trip, two-pole GFCI at 240V. Confirm available fault current, conductor sizing, and any load-neutral arrangement from the wiring diagram. A qualified electrician should resolve compatibility before installation.
