WEG CWM50-11-30V18 50A 3-Pole IEC Contactor 120V Coil 1NO/1NC Aux

The WEG CWM50-11-30V18 is a 50-amp, 3-pole IEC magnetic contactor from WEG's CWM series, featuring a 120V AC coil and built-in 1NO/1NC auxiliary contacts included right out of the box. Designed as a heavy-duty general purpose contactor, the CWM series is built for high reliability across demanding industrial applications and is rated for inductive loads up to 800 amps across the full series range.
 
Rated for 15 HP at 230V and 40 HP at 460V in three-phase applications, it handles larger motors, pumps, blowers, cranes, elevators, material handling equipment, and machining tools with confidence. The built-in 1NO/1NC auxiliary contacts make it ready for most standard control circuit wiring without needing to order additional contact blocks separately — a practical advantage on straightforward motor starter builds. The 120V AC coil fits standard North American line voltage control circuits, and screw terminals on both the power and control side keep wiring secure and accessible. Mounts on standard 35mm DIN rail or directly with screws, and carries IP20 finger protection rating.
 
Additional front and side mountable auxiliary contact blocks can be added — up to six total — for more complex control schemes. WEG thermal overload relays mount directly to the load side in ranges from 25 to 57 amps for complete motor protection. Also the authorized replacement for the obsolete GE CL06A311MJ contactor — identical dimensions and electrical ratings, straight drop-in swap.
