WEG CWB25-11-30D39 25A 3-Pole IEC Contactor 480V Coil

The WEG CWB25-11-30D39 is a 25-amp, 3-pole magnetic contactor from WEG's CWB series, featuring a 480V AC coil and built-in 1NO/1NC auxiliary contacts. Built to meet both IEC 60947 and UL 508 international standards, it's a go-to choice for industrial motor control applications where the control circuit runs at 480V — eliminating the need for a separate control transformer in many 3-phase industrial setups.
 
Rated for up to 7.5 HP at 230V and 15 HP at 460V in three-phase applications, it's well suited for motors, pumps, compressors, conveyors, and other industrial loads. The compact 45mm-wide footprint helps save valuable panel space without sacrificing performance. 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.
