industrial control products

WEG is more than a world class manufacturer of electric motors. WEG has also spent years developing and designing products used in motor control. Contactor, Starters, Enclosed Direct On Line (DOL) Starters as well as Pushbuttons and Pilot Lights are available from WEG to suit an application’s requirements.

Miniature Contactors

The CWC Series miniature contactor features more horsepower for its size than any other miniature contactor on the market. The CWC’s compact dimensions for its current rating, up to 25A, AC-3 utilization category, allows it to take up less space inside electrical enclosures while still running motors up to 10HP @ 575V. The dimensions remain the same whether the coil voltage is AC or DC making panel design and assembly easier. DC models feature low consumption coils allowing the CWC to be operated directly from a PLC without interface relays.

An extensive lineup of modular and tool-free accessories makes the CWC Series the most flexible and easy-to-use miniature contactor available today.

Standard Contactors (CWM Line)

The CWM general-purpose contactor line has been designed taking into consideration industrial duty and reliability. Rated for inductive loads up to 800A or 440kW @380/400V, WEG can offer the suitable contactor for your application.

CWM contactors allow total panel space optimization, with only a few compact frame sizes from 4 to 440kW @ 400/415V. Reducing inventory is a “snap” with CWM’s common accessories. For example, side-mounted auxiliary contact blocks are the same from 9 to 300A (AC-3) @ 440V.

Designed for extended mechanical and electrical life, dependable switching in even the most heavy-duty applications can be achieved. No matter how demanding the application, all WEG contactors are tested and approved to be used under Type 1 and Type 2 short circuit coordination. Ensuring global acceptance, all components conform to UL508 (USA and Canada), IEC60947 and CE.

All WEG contactors are manufactured to assure the highest quality manufacturing processes and component materials. This way, WEG offers reliable solutions for low-voltage applications in electric panel assemblers, OEMs, distributors and end users.

Thermal Overload Relays

RW overload relays are important equipment within the WEG Controls range of products. As usual for 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 to be used with, and as perfect complement to WEG’s mini contactors and contactors. Effectively, RW overload relays can be mounted directly to WEG mini contactors and contactors, assuring electrical and mechanical operation as an open across-the-line starter. Accessories are also available for separate mounting.

RW overload relays are fitted with fixed bimetallic parts, 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 and phase failure sensitivity protection.

Motor Protective Circuit Breaker

With the latest technology and design, MPW series provide saving panel space and suitable to be used in most applications in motor control. It combines short-circuit and motor overload protections in just one component.

These devices include a three-position rotary ON-TRIP-OFF handle, which can be padlocked in the OFF position. Designed for DIN rail mounting, while lugs for direct panel mounting are also available as accessory.

MPW Motor Protective Circuit Breakers areavailable in four models; MPW16/MPW25 (45mm), MPW65 (54mm) and MPW100 (70mm) and designed for use according to international standards, making them suitable for applications all over the world.

Enclosed Motor Starters – NEMA 4X

WEG offers non-reversing and non-combination NEMA-4X magnetic starter up to 75HP at 460V.

Featuring components that meet IEC design standards and UL horsepower ratings, including WEG contactors and overload relays, the PESW magnetic starters are ideal to help protect motors and ensure smooth operation year-after-year.

These components are assembled together in a NEMA 4X enclosure with two options off the shelf; Start/Stop Pushbutton and RESET or just the RESET button on the cover for quick and easy operation. WEG PESW starters are recommended for all single and three phase applications where across-the-line starters can be applied.

Pushbuttons and Pilot Lights

WEG has used its leading-edge technology & development capability to design CSW series line of pushbuttons, pilot lights, selector switches and accessories. These user friendly and durable Ø22mm pilot devices allow their use in several industrial applications and environments. Besides the high luminosity, the BIDL blocks have many other interesting characteristics, including long life expectancy, great performance on shock and vibration applications, extremely low power consumption and thermal dissipation.

Fast and easy assembling system

The Mounting of the contact blocks to the operator (pushbutton, selector switch or indicator) is done through a snap-on flange which ensures a fast and tight fitting. This system allows its removal in a practical and fast way, without tools. Each single block can be mounted or removed individually: to assemble, just snap the components together and a common screwdriver is all that is necessary for the disassembly. The ergonomic design of the new locking ring allows hand tightening, without the need for a screwdriver.

Contact blocks – safety and reliability

High efficiency self-cleaning contact bridges; Pure Silver Contacts (Ag100), ensure in every condition maximum reliability and to monitor control circuits at low energy levels (5mA/12V). NC Contacts with “Positive Break” system ensures the circuit interruption.

Accessories

A complete line of accessories is available, including legend plates, protection covers and lenses for pilot lights, solid and engraved caps for flush pushbuttons.
