This is the highest quality stand-alone RV fuse box we've ever seen. It is a surface-mount box that allows for wiring up to 9 independently fused DC circuits.
It's ideal for replacing a converter that contains an internal fuse panel (like older Univolts) with a converter/charger that does not (like modern Inteli-Power Converters).
Each circuit has a capacity of 20 amps with a total capacity of 85 amps. It has three positive DC input terminals and a chassis mounted ground terminal bus.
For added safety, it includes a hinged lid that snaps into place and a mounting bracket that lets air flow behind the fuse board. UL Listed.
Uses widely-available Bussman ATC fuses (available separately).
Size is 7" x 4-1/2" x 1-3/4"
Two-year warranty.
