Abstract
An operation counter arrangement is provided for a circuit interrupter for opening a high-voltage circuit-isolating device. The operation counter arrangement responds to actual operations via response to a moving contact arrangement of the circuit interrupter. The operation counter arrangement is capable of retrofit to existing circuit interrupters via replacement of an exhaust control device of the circuit interrupter. In a preferred arrangement, a count of both the total number of operations and the number of operations since the most recent maintenance is provided.
