Cylindrical ceramic solar fuse, 15 A 1000 V DC, fast-acting, non-indicating

Bussmann

Bussmann PV-15A10F 15 A 1000 V DC cylindrical line protection

SKU CH-95M2-MB2E6

A 15 A, 1000 V DC fast-acting cylindrical fuse rated for 33 kA interrupting capacity in solar PV circuits

  • 15 A fast-acting fuse protects solar strings
  • 1000 V DC rating suits high-voltage photovoltaic arrays
  • 33 kA interrupt rating at 1000 V DC handles large fault currents
  • Class gPV to IEC 60269-6 and UL 2579 for code compliance
  • Cylindrical ceramic body 1-1/2 in x 13/32 in fits standard holders

Solar circuit protection

The Bussmann PV-15A10F is a 15 A fast-acting fuse rated for 1000 V DC. It belongs to the PV-F series with a Class gPV designation for photovoltaic string protection. The cylindrical ceramic body measures 1-1/2 in length by 13/32 in diameter. It carries UL 2579, IEC 60269-6, CSA and CCC certifications.

Replacing slower or lower-rated fuses

This fuse interrupts at 33 kA, clearing faults faster than standard gG or gR types. The jump is worth it when a combiner box or inverter requires a 1000 V DC rating with a 33 kA interrupt capacity. It also matches the Littelfuse SPF and Mersen HP10M series for direct cross-reference in existing designs.

Sustained operation in combiner boxes

Under continuous load the single-element ceramic construction runs cool and maintains its calibrated opening time. The 33 kA interrupt rating holds at the full 1000 V DC without degradation. Non-indicating design means visual inspection requires a multimeter or monitoring circuit.

Questions about this item

What length and diameter fuse body fits this 15 A 1000 V DC cylindrical fuse?

The fuse body is 1-1/2 inches long and 13/32 inches in diameter with a ceramic construction.

How do I install this fast-acting gPV fuse and what step is often missed?

Insert the cylindrical fuse into a compatible gPV fuse holder rated for 1000 V DC; the common mistake is not verifying the holder interrupt rating matches the 33 kA fuse rating.

When should this non-indicating solar fuse be replaced?

Replace after any overcurrent event that causes the fuse to open, since the non-indicating design gives no visual confirmation of operation.
