Product FAQs
7 answersWhich Siemens load centers accept the Q22020CT2 breaker?
It is compatible with Siemens EQ, PL, ES, and Ultimate load centers, but the panel must specifically accept CTL type QT breakers. The busbar must be notched to accommodate the breaker's rejection clip.
What is the circuit configuration of the Q22020CT2?
It provides two independent 2-pole 20A circuits within a single unit. It features an inner 2-pole 20A circuit and an outer 2-pole 20A circuit, allowing you to feed two 240V loads from just two panel spaces.
Does the Q22020CT2 feature a common trip mechanism?
Yes, the CT2 designation indicates that both the inner 20A pair and the outer 20A pair are common trip. A fault on one leg will trip both legs of that respective 240V circuit.
How many panel spaces does this quadplex breaker require?
The Q22020CT2 requires two standard 1-inch panel spaces to provide four poles of overcurrent protection.
What is the direct replacement for the Murray MP22020CT2?
The Siemens Q22020CT2 is the direct, manufacturer-approved replacement for the obsolete Murray MP22020CT2 quadplex circuit breaker.
What does the CTL rejection feature do on this breaker?
The Circuit Total Limiting (CTL) feature prevents the breaker from being installed in load centers that are not designed to accept tandem or quadplex breakers. The panel busbar must be notched to accept the CTL rejection clip.
Is the Q22020CT2 rated for HVAC equipment?
Yes, this breaker is HACR rated for use with heating, air conditioning, and refrigeration equipment. It is also SWD (Switching Duty) rated for switching 120V fluorescent lighting loads.
