Product FAQs
8 answersIs the Murray MP260 still being manufactured?
No. Siemens phased out the Murray brand and its MP-T circuit breakers starting in 2019. The direct, UL-listed replacement for the MP260 is the Siemens Q260.
Can I use a Siemens QP breaker to replace a Murray MP260?
Yes. Siemens acquired Murray and issued an official substitution letter confirming that Siemens QP series breakers, such as the Q260, are the authorized, UL-listed replacements for Murray MP-T breakers in Murray load centers.
What are the wire capacity requirements for the MP260?
The terminal lugs accept 8-4 AWG copper or 8-2 AWG aluminum conductors. Always torque the connections to the specifications printed on the breaker label or panel wiring diagram to ensure a safe installation.
What type of trip protection does the MP260 provide?
This breaker utilizes fixed thermal-magnetic trip technology. It includes long-time (L) protection for sustained overloads and instantaneous (I) protection for rapid short-circuit response.
Can I install the MP260 in an Eaton or Square D load center?
No. The MP260 is designed specifically for plug-on installation in compatible Murray and Siemens load centers. Using it in other brands violates UL listings and creates a potential fire hazard.
Is the MP260 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 60-amp, 2-pole circuit.
Does the MP260 provide GFCI or AFCI protection?
No. The MP260 is a standard thermal-magnetic breaker. It does not include ground-fault (GFCI) or arc-fault (AFCI) protection.
How many panel spaces does the MP260 require?
As a 2-pole breaker in the MP-T frame size, it requires two standard 1-inch spaces in a compatible load center.
