WEG CWBN1-11-30D39 NEMA Size 1 25A 3-Pole Contactor 480V Coil

The WEG CWBN1-11-30D39 is a NEMA Size 1, 25-amp, 3-pole magnetic contactor from WEG's CWBN series, featuring a 480V AC coil and built-in 1NO/1NC auxiliary contacts. It meets both IEC 60947 and UL 508 international standards, giving contractors and engineers who spec by NEMA size a modern, compact contactor in the familiar Size 1 form factor — the same physical body as the CWB25 IEC series.
 
The 480V AC coil makes it a natural fit for industrial three-phase panels where the control circuit runs at the same 480V as the load — eliminating the need for a separate control transformer and simplifying panel wiring in many industrial applications. Rated for up to 25 HP at 460V in three-phase applications, it handles motors, pumps, compressors, and similar industrial loads reliably. All terminals including coil connections are front-facing for easy 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 thermal overload relays mount directly to the load side for a compact, complete motor starter assembly. Accessories are shared across the full CWB line from 2 to 50 HP at 460V, making it easy to standardize your inventory across multiple contactor sizes.
