Description
Maximizing circuit capacity in residential panels, the Q23030 is a space-saving quadplex breaker from the Siemens QT series. It delivers two 30A outer poles and two 30A inner poles, allowing installers to add circuits without a larger enclosure. This plug-on breaker mounts into Siemens and Murray load centers. Designed with CTL rejection, it substitutes for MP23030 and Q23030CT2 models. Featuring thermal-magnetic technology, it provides 10 kAIC fault protection and carries an HACR rating.Specifications

Product FAQs
7 answersWhat panels are compatible with the Siemens Q23030CT2?
It is designed for use in Siemens and Murray load centers that accept Type QT plug-on breakers. Always verify your panel wiring diagram to ensure it accepts quadplex breakers.
How many panel spaces does the Q23030CT2 require?
This quadplex breaker requires two standard 1-inch panel spaces to provide two independent 2-pole 30A circuits.
What does the 30/30A rating mean on this quad breaker?
The 30/30A rating indicates it provides two separate 30-amp, 240V circuits. The two outer poles form one 30A 2-pole circuit, and the two inner poles form a second 30A 2-pole circuit.
Are the Q23030 and Q23030CT2 the same breaker?
Yes, Q23030 is the base catalog number, while the CT2 suffix specifically denotes that both the inner and outer circuits feature a common trip mechanism. They are functionally the same for standard residential applications.
Does this breaker have a rejection clip?
Yes, the Q23030CT2 is a CTL (Circuit Total Limiting) breaker equipped with a rejection clip. It is designed to prevent installation in panel slots not rated for tandem or quadplex breakers.
Can I use this breaker to replace a Murray MP23030?
Yes. Siemens manufactures Murray breakers and has officially phased out the Murray brand. The Siemens Q23030CT2 is the UL-listed, direct replacement for the obsolete Murray MP23030 and MP23030CT2 quadplex breakers.
What happens if one side of a 2-pole circuit overloads on the Q23030CT2?
Because both the inner and outer 2-pole circuits feature an internal common trip mechanism, an overload or short circuit on one leg of either 240V circuit will automatically trip both poles of that specific circuit, disconnecting power to the entire load.
