Description

Designed to monitor electrical balance, this 30A two-pole GFCI breaker interrupts power when detecting a 5mA ground fault. It is built for residential applications requiring strict NEC compliance in areas prone to moisture, utilizing a standard pigtail neutral. This legacy component installs into standard Murray and Siemens plug-on load centers, providing a seamless hardware match. For future upgrades, it is officially replaced by the current QF230A catalog number.

Product FAQs

5 answers
Can I install the Murray MP230GF in a Siemens electrical panel?

Yes. Siemens acquired the Murray brand and officially cross-lists MP series breakers for use in standard Siemens plug-on load centers. Always verify the panel wiring diagram to confirm approved breaker types before installation.

What is the active Siemens cross-reference for the Murray MP230GF?

Siemens phased out the Murray brand name. The direct, UL-listed replacement for this 30A GFCI breaker is the Siemens QF230A or QF230. Both share the exact same physical dimensions and plug-on mounting style.

What is the ground-fault trip threshold for this breaker?

The MP230GF is a Class A GFCI breaker. It is engineered to interrupt power when it detects a ground-fault leakage current of 5mA, providing personnel protection to meet NEC requirements for wet or damp locations.

Does this breaker require a plug-on neutral panel?

No. The MP230GF features a standard pigtail neutral connection. The attached white pigtail wire must be routed and secured directly to the neutral bus bar in the load center to power the internal GFCI circuitry.

Is the MP230GF suitable for HVAC equipment?

Yes. This breaker is HACR rated, meaning it is approved for use with compatible heating, air conditioning, and refrigeration equipment that requires a 30A, 2-pole circuit with ground-fault protection.
