7AM Motor Protector

Motor Protectors

KLIXON® 7AM delivers the maximum protection in the smallest package at an excellent price. It’s the most reliable on the market, backed by the leading innovators in protection technology. Each 7AM temperature rating has a bimetal disc specifically manufactured for that rating. Each device is then calibrated and checked for opening temperature. This results in optimum snap–acting open and reset characteristics necessary to achieve consistent performance over the required cycle life. The Klixon® bimetal disc welded in a steel can provides excellent thermal sensitivity and maximum protection properties.
