WEG is one of the world's largest manufacturers of electric motors, drives and low-voltage control gear, and a major producer of industrial coatings. Our WEG collection brings together more than 19,000 WEG part numbers in one place: variable frequency drives (CFW08, CFW300 and CFW500 series), SSW soft starters, CWB and CWM contactors, RW thermal overload relays, PESW enclosed and combination motor starters, MPW motor protective circuit breakers, CSW pushbuttons and pilot devices, SRW01 smart relays, power factor capacitors, AG10 alternators, and motor spares such as fans, fan covers, flanges and terminal boxes.

The collection also carries WEG's full range of industrial coatings, including WEG powder coatings, liquid coatings, automotive refinish products, impregnation varnishes, thinners and solvents. Whether you are replacing a failed drive on a production line, building a new motor control panel or re-stocking a paint shop, Industrial Automation Co. can supply new WEG products with fast quotes and two-day shipping on lightweight parts.

WEG Product FAQ — Drives, Soft Starters, Contactors & Motor Control

Can a WEG CFW variable frequency drive be replaced with a different CFW series?
Often — as long as the voltage class, rated output current and enclosure rating match the motor and installation. Control wiring, communication options and parameter sets differ between the CFW08, CFW300 and CFW500 families, so we confirm the I/O and fieldbus requirements before recommending a cross-reference.

Do I need a soft starter or a VFD for my WEG motor?
A WEG SSW soft starter limits starting current and torque but runs the motor at line frequency once started. A CFW variable frequency drive also controls speed continuously. If the application only needs a gentle start (pumps, fans, compressors at fixed speed), a soft starter is usually the lower-cost option; if speed control or energy savings at partial load matter, choose a VFD.

Are WEG CWB and CWM contactors interchangeable?
Only when the rated operational current (AC-3), coil voltage and number of auxiliary contacts match. CWB is WEG's compact contactor line and CWM the classic line, and they use different accessories and overload relays, so we verify the frame size and coil code before substituting one for the other.

Which WEG overload relay pairs with my contactor?
WEG RW thermal overload relays are sized by current range and mount directly to a matching contactor frame. We match the relay's adjustment range to the motor's full-load current and confirm it mechanically fits the contactor you are using.

What is the difference between a WEG enclosed starter and a combination starter?
A PESW enclosed starter houses a contactor and overload relay in a NEMA enclosure. A combination starter adds short-circuit protection — a motor protective circuit breaker or disconnect — in the same enclosure, so a single unit provides disconnect, protection and control for one motor.

Do WEG powder and liquid coatings have different storage and shelf-life requirements?
Yes. Powder coatings should be kept dry and cool and used within the shelf life printed on the packaging, while liquid coatings, thinners and varnishes have their own storage temperature and pot-life limits stated on the technical data sheet. Contact us with the WEG product code and we will send the relevant data sheet.

Can you supply WEG products that are discontinued or hard to find?
Yes — alongside current production items we source superseded WEG part numbers and their recommended replacements. Send us the part number from the nameplate or label and we will confirm availability and any cross-reference.

Do WEG parts qualify for two-day shipping?
WEG products under 20 lbs. qualify for two-day shipping within the continental United States. Larger items such as enclosed panels, alternators and 200 L coating drums ship freight; contact us for a quote and lead time.
