RIS isolator is mainly intended for distribution and control circuits with
AC 50 Hz, rated voltage up to 400 V and rated current up to 125 A.
It is mainly used as the main switch in distribution assemblies and
can also be used for infrequent switching of low-power appliances
and lighting.
It is widely used in industrial and mining enterprises, high-rise
buildings, commercial and residential buildings.
