Abstract
A circuit breaker system and method having zone selective interlock features with separate restrained and unrestrained setting capability is provided. The system and method include the transmission of a selective interlock signal from a downstream circuit breaker to an upstream circuit breaker in the event of a fault condition. The upstream circuit breaker upon receipt of this signal changes the tripping response of the second circuit breaker to a restrained mode. The circuit breakers include features enabling the user to modify and adjust both the restrained and unrestrained trip curves associated with both the restrained and unrestrained modes of operation.
