Mainly used in the distributing and motor circuit
which has high short-circuit current,
and acted as main switch or master switch
infrequently operated by hand,
it is particularly suitable in the
relative high class with drawble low voltage
They provide safety isolation and protection
against overcurrent for
any low voltage electrical circuit.
1.2 Standard: IEC/EN 60947-3.
1.3 General characteristic
Unique rolling inside type contact system
