Обзор
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.
Характеристики
- Enclosed contactor and thermal overload relay assembly.
- Green start and red stop push buttons.
- CJX2-D or CJX2s contactor options with matching overload
relays. - Adjustable overload protection selected to suit the motor
током. - Detachable cover for component inspection and maintenance.

Выбор
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.
Размер
The catalogue provides separate enclosure drawings for KCQ7-09–18,
KCQ7-25–32 and KCQ7-40–93. The reference sheet below includes dimensions
and the model/relay selection table.
