The WEG CWBN series NEMA rated contactor line has been designed for industrial duty and with reliability in mind. Rated for inductive loads up to 50 Amps or 25 HP @ 460V, WEG can offer the suitable contactor for your application. Customers who are used to specifying contactors (and starters), by a particular NEMA size (size 00, 0, 1, 2), now can use the WEG CWBN series, NEMA rated contactors. Customers get the ease of choosing the product, the reliability of WEG quality, and still get the sophisticated arc quenching techniques to reduce excess heat on the contacts. Given their compact footprints, CWBN contactors allow total panel space optimization, with only a few compact frame sizes from 2 to 25 HP @ 460 V. Reducing inventory is a "snap" with CWB's common accessories. For example, side mounted auxiliary contact blocks are the same from 2 to 25 HP @ 460 V.
The characteristics of the CWB contactors make them suitable for applications in many different segments:
