Abstract
RESUMEN Un método para separar contactos soldados en un conjunto de interruptor accionado magnéticamente que incluye proveer múltiples golpes de martillo del actuador a los contactos. El método incluye hacer que los contactos se cierren usando, por ejemplo, un dispositivo de actuación manual y detectar una condición de alta corriente que ocurre cuando los contactos se cierran. El método incluye además accionar eléctricamente el actuador para abrir los contactos en respuesta a la detección de la condición de alta corriente y determinar que los contactos no se han abierto en respuesta a la activación del actuador debido a que están soldados entre sí. El método también incluye accionar eléctricamente el actuador para cerrar los contactos, cuando se determina que están soldados entre sí y accionar de nuevo eléctricamente el actuador para abrir los contactos.
