Product FAQs
6 answersWhat type of panels accept the Siemens Q23020 quadplex breaker?
This Type QT breaker is compatible with Siemens and Murray load centers that are specifically designed to accept CTL (Circuit Total Limiting) plug-on quadplex breakers. Check your panel wiring diagram to confirm Type QT compatibility.
How many panel spaces does the Q23020 require?
Despite housing four independent poles, this quadplex breaker features a space-saving design that requires only two standard 1-inch panel spaces for installation.
What circuit configuration does the Q23020 provide?
This quadplex breaker delivers a 30A pair and a 20A pair of poles within a single unit. This allows you to maximize circuit density and expand capacity in crowded enclosures without requiring additional panel spaces.
Is the Q23020 suitable for HVAC applications?
Yes, this thermal-magnetic breaker is HACR rated, meaning it is certified for safe use with heating, air conditioning, and refrigeration equipment.
Can I use the Q23020 to replace older ITE breakers?
Yes, because Siemens acquired ITE, modern Siemens Type QT breakers are compatible replacements for legacy ITE quadplex breakers in panels that accept this frame type.
Can I terminate aluminum wiring directly to the Q23020?
Yes, the standard lugs on this breaker are AL/CU rated, allowing direct termination of both copper and aluminum conductors ranging from 14 AWG to 6 AWG.
