Abstract

Un receptáculo incluye contactos separables, un mecanismo de operación estructurado para abrir y cerrar los conttactos separables, y dos circuitos de disparo. Un primer circuito de disparo a base de microprocesador incluye una primera salida que tiene una primera señal de disparo de falla de arco / falla de tierra, y una segunda salida que tiene una señal pulsada periódica. Un segundo circuito de disparo a prueba de fallas teniendo una entrada teniendo la señal pulsada periodica y una salida teniendo una segunda señal de disparo. El segundo circuito de disparo a prueba de fallas se estructura para emitir la segunda señal de disparo en respuesta a falla del primer circuito de disparo.
