Bussmann PV-250A-2XL 250A gPV High-Speed DC Fuse-Link, Bolted Connection

The Bussmann PV-250A-2XL is a 250 A high-speed gPV fuse-link engineered for DC photovoltaic circuit protection, offered across the family in ratings from DC 1000V to DC 1500V. Measuring 59 x 76 x 190 mm with a bolted (XLB) connection, this 2XL-size fuse-link is UL Listed and IEC compliant (IEC 60269) for use in solar combiner boxes, string protection, and DC disconnect assemblies. Its gPV classification means it is purpose-built to safely interrupt the sustained fault currents characteristic of photovoltaic arrays, giving installers a dependable overcurrent solution for commercial and utility-scale solar systems.

Key Features

  • Trade Size: 59 x 76 x 190 mm fuse-link body sized for standard 2XL fuse holders and disconnect switches.
  • High-Speed gPV Design: Purpose-built photovoltaic fuse class for fast, reliable clearing of DC fault currents in solar arrays.
  • Bolted Connection: XLB bolted termination style provides a secure, low-resistance electrical connection for high-current DC applications.
  • Amperage Rating: 250 A rating protects PV combiner boxes, strings, and DC disconnects from sustained overcurrent conditions.
  • DC Voltage Range: Family available in DC 1000V and DC 1500V ratings to match a wide range of solar array system voltages.
  • Compact Footprint: Product dimensions of 94 mm width x 82 mm height x 217 mm length depth suit space-constrained enclosures.

Bussmann PV-250A-2XL-B – Frequently Asked Questions

1) What is the difference between the PV-250A-2XL-B and the PV-250A-2XL-3B-15 Bussmann fuse-links?
Voltage rating is the difference. The PV-250A-2XL-B is the DC 1000V part and the PV-250A-2XL-3B-15 is the DC 1500V part. Both are 250 A gPV high-speed fuse-links in the 2XL body with a bolted connection. Match the part to your array's maximum system voltage: a 1500V string needs the -3B-15, and dropping a 1000V link into a 1500V array is a misapplication.
2) Will a 250A 2XL gPV fuse-link fit my existing fuse holder or DC disconnect?
The 2XL body measures 59 x 76 x 190 mm and is sized for standard 2XL fuse holders and disconnect switches, so it drops into any holder prepped for a 2XL bolted (XLB) link. Overall product envelope including the bolt terminations runs 94 mm width, 82 mm height, 217 mm length, which is what you need to clear inside a combiner box or enclosure. It is a bolted termination, not a blade or cylindrical cartridge, so a clip-style holder will not take it.
3) Can I use a standard AC or general-purpose fuse instead of a gPV fuse in a solar combiner box?
No. gPV is a photovoltaic-specific fuse class, built to interrupt the sustained, low-magnitude fault currents that PV arrays produce rather than the high prospective currents an AC circuit delivers. The Bussmann PV-250A-2XL is a high-speed gPV DC fuse-link rated DC 1000V to 1500V for string and array protection. A general-purpose AC fuse has no valid DC interrupting rating at those voltages and should not be substituted in a combiner box or DC disconnect.
4) Is the Bussmann PV-250A-2XL UL Listed and does it meet IEC standards for a utility-scale solar job?
It carries all three marks an engineer normally needs on a PV overcurrent submittal: UL Listed, compliant to IEC 60269, and CE Marked. That covers both North American and IEC-referenced specs, which matters on utility-scale and commercial solar where the drawing may call out either standard.
5) Why choose a bolted-connection fuse-link over a clip or blade style for high-current DC?
A bolted (XLB) termination clamps the fuse body directly to the bus or base, giving a low-resistance joint that stays tight under the continuous current a 250 A PV string carries. Clip-style contacts relax over thermal cycling and can build resistance at the contact point. For combiner boxes and DC disconnects running near their rating, bolted is what the enclosure is typically prepped for.
6) What is a 250A gPV fuse-link actually used for in a PV system?
String and array overcurrent protection, mostly. It sits in solar combiner boxes, DC disconnect switches, and fuse holders on commercial and utility-scale installations, both new construction and renewable retrofits. At 250 A it is a combiner or recombiner output device rather than an individual string fuse, which is usually a much smaller rating.
