General
WSB1-80 series MCBs are mainly applied at lines of AC
50Hz or 60Hz, rated operation voltage AC230/400V, rated
current upto 80A, for overload and short circuit protection
to the lines, also for changeover of infrequent operation to
the lines. The MCBs are used at places of commercial
office building, residential and similar building etc.
The product meets standards of GB 10963.1 and IEC
60898-1, at international advanced level.
