1 Inside (877) 789 Fax () 87 WEG Contactors CWM and CWME Series International () 07 The CWM generalpurpose contactor line has been designed taking into consideration industrial duty and reliability in mind. All contactors are manufactured to assure the highest quality manufacturing processes and component materials. This way, WEG offers reliable solutions for lowvoltage applications in electric panel assemblers, OEMs, distributors and end users. Given their compact footprints, CWM contactors allow total panel space optimization, with only a few compact frame sizes from to 7Hp@V. Reducing inventory is a snap with CWM s common accessories. For example, front & side mounted auxiliary contact blocks are the same from to 7Hp@V. Features General purpose applications; and pole versions available; Direct mounting to RW overload relay with no accessory; Direct mounting to MPW manual motor protectors with use of ECCMP accessory; Mirror Contacts for SafetyRelated Applications; Wide coil voltage selection AC or DC; Builtin auxiliary contacts up to V; Common front & side mountable auxiliary contact blocks for entire series.

For these applications the electric lifespan of a particular contactor can be estimated using the formula: Where: E= Estimated electric lifespan for mixed duty application. AC= Number of electrical operations taken from the AC Duty life curve. AC= Number of electrical operations taken from the AC Duty life curve. P= Proportion of AC operations to total operations for the application, expressed as a percentage. Inside (877) 789 Fax () 87 International () 07
