Description
Supplying two distinct 240V loads from a single two-pole footprint, the MP250230CT2 features a 50A center circuit and a 30A outer circuit. This configuration is highly effective for residential applications where panel space is limited. Utilizing a standard plug-on connection, the breaker fits securely into Murray and Siemens load centers. As the Murray line has been phased out, this component is officially replaced by the Siemens Q25030CT2. It provides reliable thermal-magnetic protection.Specifications

Product FAQs
6 answersWhat load centers are compatible with the MP250230CT2 circuit breaker?
This plug-on quadplex breaker is designed for use in both Murray and Siemens load centers. It fits securely into panels that accept MP-T or QP type breakers, saving space by providing two 240V circuits in a two-space footprint.
Is there a direct Siemens replacement for the Murray MP250230CT2?
Yes. Because the Murray brand has been phased out, the official Siemens direct replacement for this component is catalog number Q25030CT2.
How much panel space does the MP250230CT2 require?
As a quadplex circuit breaker, it requires two standard 1-inch panel spaces to provide two independent 240V circuits.
How are the 30A and 50A circuits configured on this quad breaker?
The MP250230CT2 features a 50A 2-pole circuit on the center connections and a 30A 2-pole circuit on the outer connections. This configuration allows you to supply two distinct 240V loads from a single two-pole footprint.
Is the MP250230CT2 suitable for HVAC equipment?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires a 30A or 50A 240V circuit.
Does this breaker feature common trip functionality?
Yes, the CT2 suffix indicates it features internal common trip for both the 50A center circuit and the 30A outer circuit. If an overload or short circuit occurs on one leg of either 240V circuit, both legs of that specific circuit will trip simultaneously to ensure safety.
