Murray MP115AF 15-Amp 1 Pole 120-Volt Arc Fault Circuit Interrupter

Murray AFCI plug in circuit breakers are intended for use in Murray load centers or meter combinations. The single pole Murray breakers may be used in single or 3-phase load centers and are 120V rated. To ensure the warranty on a Murray panel is not voided, the use of Murray breakers is required. The branch feeder type AFCI is for use in areas enforcing the 2002 and 2005 National Electric Code. Check with your local electrical inspector to confirm. Murray strongly recommends against the use of "used" breakers.  The installation of used breakers in a Murray panel will void the warranty on the panel.  Murray does not sell used breakers and has not approved any 3rd party sellers to do so.
