Description
Built for residential distribution, the Q23030CT2 quadplex breaker provides two separate 30A, 2-pole circuits while only occupying two standard panel spaces. This efficient design allows installers to add 240V loads without requiring a larger enclosure. Compatible with Siemens PL, ES, EQ, and Ultimate series load centers, it utilizes a standard plug-on mounting style. The unit features CTL rejection clips to ensure proper installation.Specifications

Product FAQs
8 answersCan the Q23030CT2 replace a Murray quadplex breaker?
Yes, Siemens is the successor to Murray. The Q23030CT2 is the direct, UL-listed replacement for the obsolete Murray MP23030CT2 circuit breaker.
What does the CT2 suffix indicate on this Siemens QT breaker?
The CT2 suffix means this quadplex breaker has internal common trip mechanisms on both the inner 30A pair and the outer 30A pair. This ensures that both legs of either 240V circuit will trip simultaneously during an overload or short circuit.
Does this breaker feature a CTL rejection clip?
Yes, the Q23030CT2 is a Circuit Total Limiting (CTL) breaker. It includes a rejection clip and will only seat in panel positions specifically notched to accept tandem or quadplex breakers.
Can I use the outer poles for two independent 120V circuits?
No. Because the outer poles share a common trip mechanism, a fault on one pole will trip the other. This breaker is designed to feed two separate 240V loads or multi-wire branch circuits that require a simultaneous disconnect.
Will this breaker fit in older ITE load centers?
Yes, Siemens manufactures direct replacements for legacy ITE equipment. The Q23030CT2 is backward compatible with ITE EQ load centers that accept Type QT breakers, provided the specific bus stabs allow for CTL breakers.
How many panel spaces does this quad breaker occupy?
The Q23030CT2 provides four poles of protection but only requires two standard one-inch spaces in the load center.
Is the Q23030CT2 suitable for HVAC equipment?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires a 30A, 240V circuit.
Can this breaker be installed in a plug-on neutral load center?
Yes, standard plug-on breakers like the Q23030CT2 are fully compatible with Siemens PN Series plug-on neutral load centers.
