Protection
APPLICATION
STET-60 series high breaking miniature circuit breaker has the
features of structure advanced, performance reliable, breaking
capacity high, appearance elegant and its shell and parts are made
of material with impact resistance, strong flame-retardant feature.
It is suitable to power system of 50or 60 frequency ,Ue 400V and
below, Ui 63A and below.
It is mainly applied at office building, residence, for lighting ,
power distribution and overload and short circuit protection of
equipment. Normally, it also can be used as the not frequent
transfer of power system. It conforms to the standards IEC60898and
GB10963.1.
