Product FAQs
7 answersCan the Siemens QF235A be installed in legacy Murray load centers?
Yes. Siemens has officially retired the Murray brand. Siemens QP and QPF type breakers, including the QF235A, are UL listed as direct replacements for legacy Murray MP-T and MP-GT breakers in Murray panels.
What is the difference between the Siemens QF235 and the QF235A?
The QF235A is the direct, updated replacement for the obsolete QF235. The A suffix indicates the addition of an automated self-test feature to comply with modern NEC and UL requirements for GFCI protection.
Does this breaker replace the Murray MP235GF?
Yes. Siemens QPF breakers are the UL listed replacements for Murray MP-GT ground fault breakers. The Siemens QF235A directly replaces the obsolete Murray MP235GF.
What is the ground fault trip sensitivity for this breaker?
The QF235A is a Class A GFCI breaker. It is calibrated to trip when it detects a ground fault current of 5mA, providing personnel protection for applications like spas, hot tubs, and wet locations.
How does the self-test feature operate on the QF235A?
The breaker performs an automated internal self-test periodically to ensure the ground fault detection circuitry is functioning. If the self-test fails, the breaker will trip and lock out, indicating that the unit has lost its protective capability and must be replaced.
How is the neutral connection wired for this GFCI breaker?
Because it is a pigtail neutral GFCI, the coiled white pigtail wire must be connected directly to the panel neutral bus. The load neutral wire must be landed on the breaker itself to ensure proper ground fault detection.
Can this pigtail breaker be used in a Siemens Plug-On Neutral (PON) load center?
Yes, it can be installed in a Siemens PON panel. However, because it is a pigtail-style breaker, the coiled white wire must still be manually landed on the neutral bus bar for the GFCI protection to function properly.
