Product FAQs
5 answersWhat load centers are compatible with the Siemens MP23020?
This plug-on circuit breaker is designed for use in Siemens and Murray load centers. Always verify compatibility with your specific panel's wiring diagram to ensure it accepts MP frame triplex breakers.
How many panel spaces does the MP23020 require?
This breaker features a compact half-inch per pole design. It provides two 20A single-pole circuits and one 30A double-pole circuit while occupying only two standard 1-inch spaces in the load center.
Is the Siemens MP23020 suitable for HVAC applications?
Yes, this circuit breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires this specific certification.
Is the Siemens MP23020 the same as the Murray MP23020?
Yes, Siemens manufactures the MP23020 and it serves as a direct replacement for the Murray MP23020. They share the same catalog number and are functionally identical for panel installations.
Does the MP23020 feature a common trip mechanism?
Yes, the center 30A double-pole circuit features a common trip. If one leg of the 240V circuit overloads, both poles will trip simultaneously to safely disconnect power. The two outer 20A single-pole circuits operate independently.
