This class 2 surge arrester is usually installed in distribution-box or feeder bus of UPS,protecting devices or equipment downstream. Fuse must be installed at the upstream of the surge arrester or the lightning arrester to make sure that protected system has double protection. The value of the fuse used in a surge arrester system should be matched to:
The value of FUSE should not be larger than the max.withstand capacity of the Surge Arester's backup fuse value.
Under the status of the max. current in the power supply & close loop circuit available current, the fuse should be able to disconnect when overloaded or short-circuited.
Take 1 & 2 into consideration, the fuse should be as large as possible to allow the maximum surge discharge of surge arrester.
