Description
The Siemens QE250H is a high-interrupting 2-pole breaker offering 30mA ground fault equipment protection (GFEP). Rated at 50A and 22 kAIC for 120/240V systems, it is engineered to protect commercial and residential machinery from damaging line-to-ground faults without the nuisance tripping associated with 5mA personnel GFCIs. This plug-on unit is compatible with Siemens load centers and P1 panelboards. For cross-reference, this model has been replaced by the Q250EGH in current catalogs.Specifications

Product FAQs
5 answersWhat is the ground fault trip threshold for the QE250H?
This breaker provides Ground Fault Equipment Protection (GFEP) with a 30mA trip threshold. It is designed to protect equipment like heat tracing and snow melting systems, unlike 5mA GFCI breakers which are meant for personnel protection.
How do I connect the neutral for this ground fault breaker?
The QE250H includes a pigtail neutral wire. You must route and connect this pigtail directly to the neutral bus bar in your panel for the ground fault equipment protection to function correctly.
What is the difference between the QE250 and the QE250H?
The H in the QE250H catalog number indicates a high-interrupting rating. This model provides a 22kAIC rating at 240V, while the standard QE250 is rated for 10kAIC.
Is this breaker compatible with Siemens P1 panelboards?
Yes, the QE250H features a plug-in mounting style that fits standard Siemens load centers as well as Siemens P1 panelboards.
Has the QE250H been replaced by a newer catalog number?
Yes, in current Siemens catalogs, the QE250H has been replaced by the Q250EGH. Both models provide 50A, 2-pole, 30mA ground fault equipment protection.
