Description
Designed to protect personnel from electrical shock, the Siemens QF225A is a 25-amp, two-pole GFCI breaker. It provides essential 5mA ground-fault detection for circuits near water sources that require slightly higher amperage than standard 20A lines. This plug-on breaker mounts securely into Siemens EQ, ES, and PL load centers. Equipped with a pigtail neutral, it is commonly replaced by the newer Q225GF SKU. Operating with a 10 kAIC rating, the unit includes an automated self-test feature.Specifications

Product FAQs
7 answersWhich electrical panels are compatible with the QF225A breaker?
This plug-on breaker is designed for use in Siemens EQ, ES, PL, and Ultimate load centers. It is also UL approved as a substitution for legacy Murray panels that require a 25A double-pole GFCI.
What is the ground fault trip threshold for this breaker?
The QF225A provides Class A ground fault protection, meaning it is designed to trip when it detects a current imbalance of 4 to 6 milliamps to protect personnel from electrical shock.
Does this GFCI breaker require a load neutral connection to function?
A load neutral is not required if you are powering a straight 240V circuit. However, the breaker's white pigtail wire must always be connected to the panel neutral bus bar for the internal ground fault circuitry to operate and self-test correctly.
Is the QF225A suitable for use with heating and air conditioning equipment?
Yes, this breaker is HACR rated, making it suitable for protecting heating, air conditioning, and refrigeration motor loads. It is also SWD rated for switching duty applications.
Does this breaker include an automatic self-test feature?
Yes, it features an automated self-test function as required by UL 943. The breaker continuously tests its internal electronics to ensure the ground fault protection is working properly. If a failure is detected, the breaker will trip and lock out.
What is the difference between the QF225A and the QF225AP?
There is no functional difference between the two catalog numbers. The P suffix simply denotes retail packaging, while the standard QF225A is distributed in contractor packaging.
Has the QF225A been replaced by a newer catalog number?
Yes, Siemens is transitioning their GFCI breaker line. The QF225A is commonly replaced by the newer Q225GF catalog number, which provides the exact same 25A, 2-pole Class A ground fault protection.
