Abstract
A circuit breaker system ( ) providing application specific module (ASM) instantaneous overcurrent indication is disclosed herein (FIG. ). A trip unit ( ) included in the circuit breaker system ( ) is powered by an external power supply unit ( ) in the ASM ( ). The circuit breaker system ( ) includes transmitting an indication signal ( ) from the trip unit ( ) to the ASM ( ) in response to an overcurrent condition. The indication signal ( ) triggers a first controller ( ) included in the ASM ( ), the first controller ( ) configured to cause the external power supply unit ( ) to maintain power to the trip unit ( ) for a first length for time sufficient to communicate a data corresponding to the overcurrent condition to the ASM ( ). The output of the first controller ( ) triggers a second controller ( ) included in the ASM ( ), the second controller ( ) configured to cause the external power supply unit ( ) to reset the trip unit ( ) in readiness to respond to the next overcurrent condition. The data received by the ASM ( ) may be processed to form a trip and overcurrent data set for display in a display unit ( ).
