As soon as the rotary handle starts to turn to change the breaker to the open position, before the breaker is changed to the open position, the early break contact changes from 101-104 to 101-102.

Early-Break contact CAO is used to indicate the position of the rotary handle, prior to reach the open position. Will release signal before breaker open
Early-Make contact CAF is used to indicate the position of the rotary handle, prior to reach the closed position. Will release signal before breaker close
