WEG CWB25-11-30D15 25A 3-Pole IEC Contactor 120V Coil

The WEG CWB25-11-30D15 is a 25-amp, 3-pole magnetic contactor from WEG's CWB series, featuring a 120V AC coil and built-in 1NO/1NC auxiliary contacts. It meets both IEC 60947 and UL 508 international standards, making it a reliable choice for a wide range of industrial motor control and circuit switching applications.
 
Rated for up to 7.5 HP at 230V and 15 HP at 460V in three-phase applications, it handles motors, pumps, compressors, conveyors, and similar industrial loads with confidence. The 120V coil makes it a natural fit for control circuits running on standard line voltage, eliminating the need for a step-down transformer in many setups. All terminals including coil connections are front-facing for easy access during installation and troubleshooting, and the unit mounts on standard 35mm DIN rail or directly with screws.
 
Up to four additional front-mounted auxiliary contact blocks can be added as needed, and WEG RW27-2D thermal overload relays mount directly to the load side for a compact, complete motor starter assembly. For reversing applications, WEG's zero-width mechanical interlock system lets you interlock two CWB contactors side by side without using any extra panel space. This is also the direct authorized replacement for the legacy WEG CWM25 contactor — identical electrical ratings, straight drop-in swap.
