Abstract

Un dispositivo de interrupción de circuito que tiene un circuito auto-monitoreo para probar automáticamente diversas funciones y estructuras del dispositivo. El circuito de auto-monitoreo inicia una rutina de auto-monitoreo que, entre otras cosas, establece una falla de auto-prueba ya sea durante la media-onda positiva o negativa, o ambas, de un ciclo de potencia de CA y determina si los mecanismos de detección dentro del dispositivo detectan adecuadamente la falla de auto-prueba. Una señal de detección temprana indica que la falla de auto-prueba fue detectada correctamente sin interferir con la operación normal de los circuitos de detección y sin causar una falsa desconexión dentro del dispositivo. La funcionalidad adicional del circuito de auto-monitoreo permite la verificación automática de que el dispositivo esté correctamente cableado, es decir, no esté mal cableado, y determina si el dispositivo ha llegado al final de su vida útil.
