CWC Series Miniature Contactors
Features
• Rated up to 15hp @ 460V
• Direct mounting to the WEG RW17D
overload relay
•Frame size is identical for
AC and DC coil contactors
up to 16A (CWC07-16).
•CWC025 frame available
with AC coil only
•Heavy-duty operation
•Tool-free DIN-rail mounting
• WEG 18-month warranty
•Snap-on accessories
•DC coil low consumption:
1.7–2.7 W
•DC coil standard consumption:
2.6–3.7 W
• Mirror contacts per IEC 60947-4-1
(Built-in N.C. and N.C. auxiliary
contacts)
The CWC series mini contactors are a complete
solution for switching and controlling motors. The
CWC’s compact dimensions for its IEC current
rating, up to 22A, AC-3 utilization category, allows
it to take up less space inside electrical enclosures
while still maintaining a powerful 15hp @ 460V.
Dimensions of the 7A to 16A contactors are the same
for both AC or DC coil voltages, making the panel
design and assembly easier. DC models feature low
consumption coils allowing the CWC to be operated
directly from a PLC without interface relays.

Overload Relays Features
RW overload relays are an important
part of WEG controls’ range of
products. As usual in WEG products, an
extended operational service life is one
of the main features you can find in RW
overload relays.
WEG’s RW class 10 thermal overload
relays are designed for use with, and as
perfect complement to, the CWC miniature contactors.
RW relays are available in compact
frame sizes from 0.28 A to 32A.
Mounting an RW series overload relay
directly to a WEG CWC miniature
contactor creates an across-the-line
starter capable of controlling motors
from fractional to 15hp @ 460V.
Standards and Approvals
•IEC 60947 and VDE 0660.
•cULus listed file no. E189202
•CE marked low voltage directive
2006/95/EC
•Marine
Modern Architecture
Previous models of open overloads with
“heaters” encounter problems in the
field, including:
•Inaccurate trip point, because of uneven
screw tightness when installed on
individual phases
•Ambient problems, such as dust and
other contaminants, because of their
open design
•Inability to protect in case of single
phase failure
•Nuisance tripping, because no
temperature compensation is possible.
The modern design of WEG overload
relays solves all of these problems.
RW overload relays are fitted with fixed
bimetallic elements, which eliminate
any need for heater elements for field
installation or future upgrading to a
more efficient motor. All sizes provide
complete motor protection by offering:
•Ambient temperature compensation
(-4°F to +140°F)
•Phase loss sensitivity protection
•Current unbalance sensitivity
Dial FLA Setting
The trip-current is set via an adjustable
dial designed with the motor’s full load
current (FLA) in mind.
Temperature Compensation
Auxiliary Contacts
(N.O. - N.C.)
Because RW overload relays include a
fourth bimetallic strip in addition to the
three that are directly heated by the motor
current, ambient temperature variations
in the range of -4ºF to +140ºF are no
obstacle for accurate protection of your
motors even in the toughest conditions.
Phase Loss Sensitivity
WEG overload relays include standard
phase failure sensitivity protection. This
feature ensures fast tripping in case of
phase loss, protecting your motor and
avoiding expensive repairs.
Multi Function Button “R”
The programmable RESET button can
be selected to operate in a Manual or
Automatic mode, with or without TEST
capabilities of the isolated “trip” N.C.
and “alarm” N.O. auxiliary contacts. The
“R” multifunction RESET / TEST button
can be set in four different positions:
•H (manual RESET only)
•HAND (manual RESET/TEST)
•AUTO (automatic RESET/TEST)
•A (automatic RESET only)
In HAND and AUTO positions, when
gray R button is pushed, both N.O.
97-98 and N.C. 95-96 contacts change
state.

These tripping characteristics show the tripping of
RW overload relays in relation to the current. They
show the mean values of the tolerance ranges at an
ambient temperature of 20ºC (68ºF), starting from
cold state. The tripping time of the overload releases at operational temperature is reduced to approximately 25% of the values shown. Under normal
operational conditions, all three phases of the RW
relays should be loaded.
