Bussmann PV-125A-01XL-15 – Frequently Asked Questions

1) Can the Bussmann PV-125A-01XL-15 fuse be used on a 1500V DC solar array?
Yes. The PV-125A-01XL-15 is rated 1500V DC at 125A, which covers utility-scale and commercial arrays built on 1500V string architecture. It is a DC-only PV fuse-link, so don't apply it to AC circuits.
2) What does the gPV rating on a solar fuse actually mean for my combiner box?
gPV is the IEC 60269 utilization category for full-range photovoltaic fuses, meaning the PV-125A-01XL-15 clears both small persistent overloads and high fault currents on a DC string circuit. That is what you want in a combiner box or on inverter input, where reverse current from parallel strings can sit just above the string rating for long periods. A general-purpose class fuse is not a substitute.
3) Is 33 kAIC enough interrupting capacity for my PV combiner?
The PV-125A-01XL-15 carries a 33 kAIC interrupting rating at its 1500V DC rating. Compare that against the available fault current your array can deliver at the fuse location, including any battery or grid-tied contribution through the inverter. On a string PV source alone, available fault current is typically a small multiple of Isc, so 33 kAIC gives substantial headroom.
4) What fuse holder does the 01XL body size fit?
The PV-125A-01XL-15 is an 01XL body size fuse-link, so it mounts in holders and disconnects prepped for 01XL high-speed PV fuse-links. Size 01XL is a longer variant of the 01 square-body family used for 1500V DC duty, so an 01 holder built only for the shorter body will not accept it.
5) How much heat does a 125A gPV fuse put into a combiner enclosure?
Figure 48 watts of dissipation per fuse at rated current for the PV-125A-01XL-15. Multiply that by the number of fuses in the enclosure when you size ventilation or apply the holder manufacturer's thermal derating; a fully loaded combiner with several of these is a real heat source in a rooftop or desert ambient.
6) Will this Bussmann PV fuse pass inspection on both a US and an overseas solar job?
It is UL Listed, certified to IEC 60269, and CE marked, which covers North American and international code paths with one part number rather than stocking two.
7) Is the PV-125A-01XL-15 fast-acting or time-delay?
High-speed, fast-acting. The element is built to clear fault current quickly to protect inverters and combiner wiring, so do not specify it where you need a time-delay curve to ride through motor or transformer inrush.
8) Is 125A the right size for a PV string fuse?
125A is well above typical single-string duty. The PV-125A-01XL-15 is sized for combiner output, sub-array feeders, or inverter input where many strings are paralleled, not for individual string protection, which usually lands in the 15A to 30A range. Check the exact part number when ordering, since the amperage is baked into it.
