Product FAQs
6 answersWhich load centers are compatible with the MP120DF circuit breaker?
This breaker is designed specifically for use in Murray plug-on load centers. It is not interchangeable with Square D, Eaton, or GE panels.
What is the direct replacement for the Murray MP120DF?
Siemens has phased out the Murray brand. The direct, UL listed replacement for the MP120DF is the Siemens Q120DF, which is approved for use in the same Murray load centers.
Does the MP120DF require a pigtail neutral connection?
Yes, this breaker features a pigtail neutral wire that must be connected directly to the neutral bus bar in the panel to ensure proper AFCI and GFCI operation.
How do the LED indicators on the MP120DF help troubleshoot a tripped circuit?
The LED indicators diagnose the cause of a trip. If the top LED is illuminated, it indicates an arc fault. If both LEDs are lit, it indicates a ground fault. If no LEDs are lit, the breaker tripped due to a standard overload or short circuit.
Does this dual function breaker include a self-test feature?
Yes, the MP120DF includes an automatic self-test and lockout feature that continuously verifies the AFCI and GFCI protection is functioning correctly, as required by UL 943 standards.
What specific protection does this dual function breaker provide?
It combines Combination Type Arc-Fault Circuit Interrupter (AFCI) and Class A 5mA Ground-Fault Circuit Interrupter (GFCI) protection into a single device, meeting NEC requirements for areas like kitchens and laundry rooms.
