NC8 series AC contactor is applied to circuits with AC
current frequency of 50 Hz or 60 Hz, rated operational
voltage up to 690 V and rated operational current up
to 500 A. It is used for remote making & breaking circuits,
and can also be used with proper thermal overload relay
together as an electromagnetic starter to protect circuits
from overload.
