Cooper Bussmann, the leader in critical circuit protection, power management and electrical safety, has introduced a new series of NH1 square bodied photovoltaic fuse links. With ratings up to 1000Vdc, these are the smallest NH style fuse links to achieve this rating, and represent a significant breakthrough in fuse link design and performance.
The new NH Series offers the most comprehensive range of NH size fuse link solutions on the market with amp ratings from 50A to 160A. Designed specifically to protect and isolate PV array combiners boxes, recombiners boxes and disconnects, these compact fuse links 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 link that meets global acceptance.
The compact size 75 x 53 x 52mm – and bladed mounting options permit easy design and installation without increasing the footprint. Optional microswitches easily permit integration with system monitoring schemes.
Ben Rooke, product manager, comments: The use of higher voltages, particularly up to 1000Vdc, 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 and are able to be easily packaged. By achieving ratings up to 1000Vdc, the entire NH Series of Solar PV fuse links can deliver on both counts with protection performance and packaging.
He continues: We plan to exhibit the NH1 PV fuse links 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 NH Series of PV fuse links, Cooper Bussmann is providing an unrivalled choice of protection for PV system manufacturers, while increasing the scope for higher power systems to be protected.
