WEG CWC012-10-30V18 12A 3-Pole Mini Contactor 120V Coil

The WEG CWC012-10-30V18 is a 12-amp, 3-pole miniature magnetic contactor from WEG's CWC series, featuring a 120V AC coil and a built-in 1NO auxiliary contact. Built to IEC 60947 and UL 508 standards, it's one of the most compact contactors in WEG's lineup — measuring just 2.28 x 1.77 x 2.05 inches — yet it delivers more horsepower per size than any other miniature contactor on the market, rated up to 15 HP at 460V across the CWC series range.
 
The tiny footprint makes the CWC012 ideal for space-constrained control panels, machine control cabinets, and automation enclosures where a full-size contactor simply won't fit. Despite its small size it's a fully capable switching device — handles motors, small pumps, fans, and other three-phase loads up to its 12-amp rating with confidence. The 120V AC coil fits standard North American line voltage control circuits, and the screw terminal design keeps wiring straightforward. IP20 rated for finger protection against accidental contact.
 
The CWC series mounts directly to WEG's RW17D overload relay and MPW25 manual motor protector, making it easy to build a complete, compact motor starter assembly. DIN rail mounting snaps on quickly for fast panel installation.
