Product FAQs
7 answersWhat load centers are compatible with the QF125A?
This breaker mounts into Siemens EQ, ES, PL, and Ultimate load centers. It is also backward compatible with legacy ITE EQ series panels.
What level of ground fault protection does the QF125A provide?
It provides Class A ground fault protection, which trips when a ground fault of 5mA is detected. This meets NEC requirements for personnel protection.
How is the neutral connection wired on this breaker?
The QF125A features a pigtail neutral wire. The pigtail must be connected directly to the neutral bus bar in the load center to ensure the GFCI circuitry functions correctly.
Does this breaker include a self-test feature?
Yes, modern Siemens QF series GFCI breakers include an automatic self-test and lockout feature to ensure continuous safety compliance with UL 943 standards.
Can I use this 1-pole GFCI breaker for a multi-wire branch circuit?
No. As a 1-pole GFCI breaker, it is designed for single 120V circuits. Multi-wire branch circuits sharing a neutral require a 2-pole GFCI breaker to function without nuisance tripping.
Is the QF125A HACR rated?
Yes, Siemens QP and QF series breakers are HACR rated, making them suitable for use with compatible heating, air conditioning, and refrigeration equipment.
What is the difference between the QF125A and a standard QP breaker?
The QF125A includes Class A 5mA ground fault protection and a pigtail neutral, whereas a standard QP breaker only provides thermal-magnetic overcurrent and short-circuit protection.
