Description
Providing essential 5mA ground-fault protection, the Siemens QF250P is a 50A, 120/240V breaker built for wet or damp location circuits. It utilizes thermal-magnetic trip technology to defend against overloads and short circuits while continuously monitoring for dangerous ground faults. Compatible with Siemens EQ, EQL, SEQ, EQG, PL, and ES series load centers. This plug-on breaker features a pigtail neutral, self-test functionality, and serves as an exact replacement for the legacy QF250.Specifications

Product FAQs
6 answersWhich load centers are compatible with the QF250P breaker?
It is designed for Siemens EQ, EQL, SEQ, EQG, PL, and ES series load centers. Because it is a 2-pole breaker, it requires two standard 1-inch bus spaces for installation.
How is the neutral connection handled on the QF250P?
This breaker utilizes a pigtail neutral. During installation, the attached coiled white wire must be routed and secured directly to the neutral bus bar in your panel to enable the ground-fault circuitry.
What type of ground-fault protection does this breaker offer?
The QF250P provides Class A ground-fault protection. It is calibrated to trip when it detects a ground-fault current of 5mA, making it suitable for protecting circuits in wet or damp locations.
Can the QF250P be used for hot tub or spa installations?
Yes, its 50A capacity and Class A 5mA ground-fault protection make it a standard choice for hardwired hot tubs, spas, and pools that require a dedicated 240V GFCI circuit.
Is the QF250P a suitable replacement for older Siemens 50A GFCI breakers?
Yes, the QF250P is a direct replacement for the legacy Siemens QF250. It upgrades the older design by incorporating modern self-test functionality.
Does the QF250P have an automatic self-test function?
Yes, it features an integrated self-test capability that continuously monitors the internal electronics. This ensures the ground-fault protection remains active and reliable over the lifespan of the breaker.
