Product FAQs
7 answersWhich load centers are compatible with the QF250AH breaker?
This breaker is designed for use in Siemens PL, ES, EQ, and Ultimate series load centers. It requires two spaces for installation.
What is the ground fault trip threshold for this breaker?
The QF250AH provides Class A ground fault protection, meaning it is designed to trip when it detects a ground fault current of 5mA.
What is the difference between the Siemens QF250A and the QF250AH?
The H in the catalog number indicates a higher interrupting rating. The QF250AH is rated for 22kAIC at 240V, whereas the standard QF250A is rated for 10kAIC.
Does the QF250AH replace older Siemens GFCI models?
Yes, the QF250AH is the direct replacement for the older QF250H model, offering the same 50A capacity and 22kAIC rating with updated self-test features.
How is the neutral connected on the QF250AH?
This breaker features a pigtail neutral connection. The coiled white wire must be connected directly to the neutral bus bar in your load center for the ground fault protection to function properly.
Can this 50A GFCI breaker be used for a hot tub or spa panel?
Yes, 50A two-pole GFCI breakers like the QF250AH are commonly installed in spa panels to provide the required ground fault protection for hot tubs and spas.
Does this breaker provide both arc fault and ground fault protection?
No, the QF250AH is a dedicated Ground Fault Circuit Interrupter (GFCI). It does not provide Arc Fault Circuit Interrupter (AFCI) or dual-function protection.
