“A major reason for contactor failure is contact arcing. Arcing occurs upon opening and closing of the contacts. This results in pitting or even welding of the contacts, and eventually premature contact failure and even motor failure. An easy solution to this problem is to add an arc suppressor to the contactor. When properly connected to the contactor the arc suppressor detects the nascent arc as it forms and suppresses its energy. The resultant arc energy passing through the contacts is reduced to a few microjoules as compared to the normal hundreds of milijoules or more. This is a substantial reduction of arc energy, and can result in extending contactor life by ten times…not to mention better protection of motors!”
