4. WEG - CONTACTORS AND
The CWM contactors are mainly used for
controlling 3-phase motors up to 75HP at 460V in
accordance with their characteristics utilization
data. Available in 11 contactor ratings for the USA
market, the CWM line offer high reliability with long
mechanical and electrical life. Designed with
features that make them easier to install, common
accessories for flexible configuration and low
inventory, the CWM contactors can be quick
mounted on DIN rail or fixed with screws. These
components conform to international standards
(UL508, CSA and IEC60947) and have the CE
marking to ensure global acceptance.

The RW_D thermal overload relays are designed for use with CWM
contactors. They are fitted with fixed bimetallic elements Class 10, ambient
compensated temperature, and a differential mechanism for single-phase
sensitivity, hence, providing thermal protection to the motors. The setting
current range is adjustable to motor nominal current. The programmable
RESET button can operate in a Manual or Automatic reset mode.

Shown in tripping curve from cold condition. Tripping values from warm condition (rated current) reduces the tripping time to approximately 25% (middle value for all
currentrange).
The characteristic curves of tripping class 10 (average values) and the performance under operation are replicated from RW_D thermal overload relays.
For more information, please contact WEG.

OPEN STARTERS
The WEG open starters consist of the CWM contactor and the RW
overload relay, which both of them must be ordered separately. The
compact direct mounting of the overload relay on the CWM contactors
reduces the panel space required. Used for full voltage starting and
stop of AC motors, the thermal overload protection is guaranteed by
the bimetallic overload relay, and a variety of accessories are available
to allow flexibility in achieving most application needs.
