Cooper Bussmann 600vDC Class RK5 solar fuses
By Anthony Capkun
Cooper Bussmann says its new PVS-R solar fuse provides high amp ratings with the required fast-acting response to low photovoltaic DC faults. The fuse is the first fuse of its kind, boasts Cooper, to achieve a UL 2579 listing for “Low-Voltage Fuses – Fuses For Photovoltaic Systems”. With a dual 600vAC/DC rating, the PVS-R is designed to withstanding high and low ambient temperatures, routine cycling, and opening under low-level fault current conditions. Available in ratings from 20-600 amps, the PVS-R fuse is suited for use in recombiner boxes and DC safety switches that operate at higher current levels, but experience the same low-level fault current conditions as combiner boxes and PV strings and arrays.
