Disconnecting arrangement for the main current path of a power circuit breaker.

摘要

A primary disconnect assembly for a circuit breaker. The assembly includes a plurality of contact fingers for engaging the terminals of a bus bar assembly. The terminals and fingers are configured such that the terminals each include depressions adapted to accept the contact portions of the contact fingers. This configuration provides at least two contact locations between each contact finger and terminal. Additionally, this configuration increases the force required to slide the fingers relative to the terminals.
