Designed to meet NEC codes, the Siemens Murray MP250GF provides essential 5mA ground-fault protection. This 50A, two-pole GFCI breaker secures heavy-duty residential loads in damp environments like hot tubs. It installs seamlessly into legacy Murray and Siemens load centers, offering an exact fit. While this remains a legacy part, it has been officially replaced by the Siemens QF250A. The breaker features a 10 kAIC interrupting rating and utilizes a reliable thermal-magnetic trip unit.
What is the Siemens replacement for the Murray MP250GF?
Siemens phased out the Murray brand and replaced the MP250GF with the Siemens QF250A. The QF250A is the UL listed direct replacement for use in Murray load centers.
Can I install the MP250GF in a Siemens load center?
Yes. Because Siemens manufactured Murray products, this breaker is UL listed for use in both Murray and Siemens plug-on load centers.
Is the MP250GF rated for personnel protection or equipment protection?
This breaker provides Class A ground fault protection, meaning it trips at a 5mA threshold. It is designed for personnel protection in wet locations such as pools, spas, and outdoor circuits.
How is the pigtail neutral connected on this GFCI breaker?
The coiled white pigtail wire must be connected directly to the neutral bus bar in the panel. This powers the internal GFCI circuitry, allowing the breaker to monitor for ground faults.
How do I wire a straight 240V load that does not have a neutral wire?
For a strict 240V load without a neutral, connect the two hot wires to the breaker lugs and leave the load neutral lug empty. You must still connect the breaker's white pigtail to the panel neutral bus for the GFCI to function.
Can I use this 50A GFCI breaker for a hot tub panel?
Yes, a 50A 2-pole GFCI is the standard requirement for many residential hot tubs and spas. Always verify the manufacturer specifications of your spa to confirm the 50A rating is appropriate.
