Product FAQs
8 answersWhich electrical panels are compatible with the Siemens Q23050 quadplex breaker?
This QT series breaker is designed for use in Siemens load centers that accept Type QT breakers, including EQ, Ultimate, PL, and ES series panels. Always verify your panel's wiring diagram to ensure it allows for quadplex or tandem breakers.
Can I install the Siemens Q23050 in a GE or Square D panel?
No. Siemens QT breakers are not interchangeable with other brands like GE or Square D. Using this breaker in a non-Siemens panel can void the UL listing and compromise the safety of your electrical system.
How much panel space does the Q23050 quadplex breaker require?
This quadplex breaker provides two independent double-pole circuits (one 30A and one 50A) while occupying only two standard 1-inch panel spaces.
Does the Siemens Q23050 feature CTL rejection?
Yes, this breaker includes a Circuit Total Limiting (CTL) rejection clip. It can only be installed in panel positions specifically notched to accept CTL tandem or quadplex breakers, preventing the overloading of the panel's maximum circuit capacity.
What is the difference between the Siemens Q23050 and the Q23050CT2?
The Q23050 is a standard quadplex breaker with independent trip functionality, while the Q23050CT2 features a common trip mechanism on both the inner and outer pairs. The Q23050CT2 is often used as a direct replacement when common trip functionality is required by local electrical codes.
Can this breaker replace older ITE or Gould quadplex breakers?
Yes. Siemens acquired ITE and Gould, and the current Siemens QT series serves as the direct, UL-listed replacement for legacy ITE and Gould quadplex breakers with matching specifications.
Is the Siemens Q23050 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 equipment that requires this specific certification.
How does the thermal-magnetic trip mechanism in the Q23050 protect circuits?
The thermal component responds to prolonged overloads by heating a bimetallic strip that trips the breaker, while the magnetic component provides instantaneous tripping in the event of a severe short circuit.
