VIOX KCQ7 electromagnetic motor starters combine an AC contactor,
thermal overload relay and start/stop push buttons in an enclosure. They
are designed for direct starting and stopping of three-phase
squirrel-cage induction motors, with AC-3 frame currents from 9 to 93 A
and rated operating voltages up to 660 V.

ရွေးချယ်မှု
Select the frame by motor voltage and AC-3 duty, then select an
overload-relay setting range that includes the motor nameplate current.
Frame current is not the relay adjustment setting. The overload relay
does not replace coordinated short-circuit protection.
The larger KCQ7-40–93 enclosures must not be treated as IP55. Choose
the enclosure protection appropriate to the installation environment and
specify it in the quotation request.
