Abstract
An improved electrical interruption apparatus provides an improved wear indicator that is configured to depict an amount of wear that has been experienced by a set of separable contacts of a vacuum interrupter. At an easily visible location on a drive rod of the circuit interruption apparatus, the wear indicator indicates the extent to which the set of contacts have degraded. The wear indicator is attached to a spring-loaded over-travel mechanism that engages together the set of electrical contacts.
