Can someone provide any data which indicates the number of operating cycles a NEMA Size 1 or 2 contactor will exhibit? The Size 1 starter has a 27A rating and the Size 2 has a 45A rating. In my efforts to draw conclusions as to whom has the best contactor operating cycle rates for my application, what would be the actual cycle rates in number of operations for the two contactors? Are there any personal issues anyone has using a particular manaufacturer contactor such as Allen Bradley, Cutler Hammer/Eaton Electric, Siemens or Square D NEMA contactors?
