Replacement fuse adapter for the MNPV3 and MNPV2-MC4 combiners. If the adapter that came with your MNPV3 or MNPV2-MC4 is cracked or broken, this replacement will snap into the combiner. A broken adapter can be very destructive to your system because it can allow rain water to leak into the combiner box. This is an easy fix that will prevent you a lot of costly repairs of your system wiring.
