The Auto- reclosing relay is designed with micro processor based electronic CPU, which can be applied for any distribution line either coordinating with synchronizing relay or bus voltage supervising relay. As setting range is wide, the reclosing relay may coordinate with other protective relay or system easily. Since the relay has a self checking. it can be shown the error message on the front plate df the reley as soon as detected. There is s delay timer which discrepanoy time detween main and aux. contact of circuit breaker con be adjusted.
