The Breaker Rating Module is designed to streamline the otherwise tedious work of checking the rating of circuit breakers against the short circuit currents they need to interrupt. The Breaker Rating Module has been merged into the main OneLiner executable since Version 11. If you have a license for the Breaker Rating Module, your program key will enable the Check | Circuit Breaker Short Circuit Rating command.
You can find additional information on the breaker-rating feature by executing the Help | Breaker Rating Application Guide Contents command in OneLiner.
