Product FAQs
6 answersHow are the 20A and 30A circuits configured on the MP220230CT2?
This quadplex breaker features a 20A 2-pole circuit on the outer poles and a 30A 2-pole circuit on the inner poles. Both the 20A and 30A circuits utilize internal common trip mechanisms for 240V applications.
How many panel spaces does the MP220230CT2 require?
This quadplex breaker provides two independent 2-pole circuits (one 20A and one 30A) while only occupying two standard 1-inch panel spaces.
Which load centers are compatible with the MP220230CT2?
This plug-on quadplex breaker is designed for use in legacy Murray load centers and compatible Siemens enclosures that accept MH-T or MP-T frame types. It must be installed in panel spaces that are approved for tandem or quad breakers.
What is the direct Siemens cross-reference for the legacy Murray MP220230CT2?
For newer installations or panel upgrades, the legacy Murray MP220230CT2 has been superseded by the Siemens Q22030CT2. Both models share the exact same 20A and 30A quadplex configuration and plug-on mounting style.
Are the inner and outer circuits on the MP220230CT2 common trip?
Yes, the CT2 suffix indicates that both the 20A outer circuit and the 30A inner circuit feature independent common trip mechanisms. A fault on one leg of either circuit will trip both poles of that specific circuit simultaneously, ensuring safe operation for 240V loads.
Is the MP220230CT2 suitable for use with HVAC equipment?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires a 20A or 30A 240V circuit.
