Fuses and fuse holders for photovoltaic DC circuits
This range covers fuses and fuse holders for photovoltaic installations. It includes 2-pole fuse bases and gPV fuse links, all rated for 1000V DC. The products protect PV strings and DC circuits against overcurrent. They are intended for installers and electrical contractors who build or service solar systems.
What you will find in this category
- 2-pole fuse bases for 10x38mm cartridges: 32A, 1000V DC (Hager version 690/1000V DC), IP20.
- Fuse base 30A, 1000V DC, category DC-20B, with optical trip indicator and fuse failure notification.
- Fuse links for PV protection: Eaton gPV 10x38 12A and Mersen HP10M15 15A, both 1000V DC.
How to choose
- Voltage: check that the rated voltage suits the string. All products here are rated for 1000V DC.
- Current rating: fuse links are 12A or 15A. Fuse bases are rated 30A or 32A.
- Fuse size and characteristic: the 32A bases take 10x38mm cartridges. Use gPV fuse links designed for photovoltaic use.
- Indication: the 30A DC-20B base has an optical trip indicator. The Hager L502PV base has no optical indicator.
- Mounting and connection: the CFPV-32 base fits TH-35 rail and accepts terminals of 0.5-10 mm². Its dimensions are 36x78x60 mm.
Typical applications
These products protect and isolate photovoltaic strings. The fuse bases suit series-configuration PV installations. The gPV fuse links handle high load cycles and reverse current. The Mersen HP10M series is designed for continuous temperature and current cycling. Eaton fuses are intended for systems operating in extreme ambient temperatures.
Frequently asked questions
Which fuse links fit the 32A fuse bases?
The 32A fuse bases in this range are designed for 10x38mm cartridges. The Eaton gPV 10x38 12A fuse link is one such size. Check the dimensions of any other fuse link before ordering.
Which fuse base shows when a fuse has tripped?
The 30A, 1000V DC, 2-pole DC-20B base has an optical trip indicator and fuse failure notification. The Hager L502PV base lists no optical indicator.
What is the ingress protection of the fuse bases?
The 32A bases, the 32A CFPV-32 and the Hager L502PV, are rated IP20. This protects against access to hazardous parts by hands or solid objects.
