Product FAQs
6 answersWhat load centers are compatible with the QF250?
This breaker installs into Siemens PL, ES, EQ, and Ultimate load centers using a standard plug-on connection. It is also compatible with many legacy ITE load centers that accept QP-type breakers.
What is the ground fault trip threshold for this breaker?
The QF250 provides Class A ground fault protection, meaning it is designed to trip when it detects a ground fault current imbalance of 4 to 6 milliamps.
How is the neutral connection handled during installation?
It features a factory-installed pigtail neutral wire. This white wire must be connected directly to the neutral bus bar in your load center for the ground fault protection to function correctly.
Does the load circuit require a neutral wire for the GFCI to work?
A load neutral is not strictly required on the circuit if you are running a straight 240V load. However, the breaker's white pigtail neutral must always be connected to the panel neutral for the internal GFCI sensor to operate.
Can this breaker be used for hot tubs and spas?
Yes, providing 5mA Class A personnel protection, this 50A GFCI breaker is commonly used for demanding wet-location applications like hot tubs, pools, and spas.
Is there a self-testing version of this breaker available?
Yes, Siemens has transitioned to newer models with automated self-test capabilities. The QF250A is the direct self-testing replacement for the legacy QF250.
