WENC PV DC Combiner Box

A populated DC combiner box for the string side of a rooftop or ground-mount array — fuses on both polarities, an isolating DC breaker for maintenance, and a 1000V surge protector, in an IP65 enclosure rated for outdoor UV exposure.

WPV-FU Photovoltaic Fuse Link
DC Protection Devices

WPV-FU Photovoltaic Fuse Link

gPV fuse links in the two sizes the PV market actually uses: 10 × 38 for 1000V systems and 10 × 85 for 1500V. Both interrupt in under a millisecond and are rated for the full-range duty a string fuse has to cover.

WPV32 Photovoltaic Fuse Holder
DC Protection Devices

WPV32 Photovoltaic Fuse Holder

DIN-rail holders for the matching PV links, at 1000V and 1500V. The 1000V version carries a blown-fuse indicator, which is what makes a fault findable on an array without pulling every holder.

WPV32-1085 Photovoltaic Fuse Base

The 1500V half of the fuse pairing: a DIN-rail base for the 10 × 85 cartridge, supplied without the fuse so the rating is chosen against the string. Where the 1000V holder carries a blown-fuse indicator, this one does not, which is worth knowing before it goes into an array that has to be faultfound from the front.
