Cooper Bussmann is launching a new range of XL Style, square bodied fuse links with ratings up to 1500Vdc. This is the highest single voltage rating ever achieved by a fuse manufacturer in this package size, and represents a significant breakthrough in fuse design and performance.
With PV system OEMs manufacturing higher voltage systems, the move to a voltage rating of 1500Vdc is timely. The new XL Style offers the most comprehensive range of fuse protection solutions on the market with ampacities from 50A to 630A at rated voltages of 1000, 1200 and 1500Vdc. The highest rated fuse at 1500Vdc is 400A, providing protection to higher power inverters.
Designed specifically to protect and isolate PV array combiners and disconnects, these high performance fuses are capable of interrupting low overcurrents associated with faulted PV systems reverse current, multi-array faults and meet the IEC 60269-6 (gPV) standard requirements. UL and CCC accreditation will follow, allowing the selection of one fuse that meets global acceptance. The compact size and bladed or bolted mounting options permit easy design and installation without increasing the footprint.
The high grade ceramic used in the fuse body has a maximum temperature withstand of over 1000°C that reduces heat generation and facilitates low power loss. Ben Rooke, product manager, comments: The use of higher voltages, particularly up to 1000Vdc at present and 1500Vdc in the near future, is becoming the global norm.
This in turn puts pressure on PV system OEMs to source and install overcurrent protection solutions that are capable of meeting their requirements. The XL Style is tomorrows solution today, delivering unsurpassed performance in a compact package. He continues: We plan to exhibit the XL Style fuses globally at the various InterSolar trade shows and demonstrate just what a significant breakthrough this advanced photovoltaic fuse is.
With the launch of the new XL Style of PV fuse links, Cooper Bussmann is providing an unrivalled choice of fuse protection for PV system manufacturers, while increasing the scope for higher power systems to be protected. Ends
