Mains Monitoring Relay, The NKR F1 monitors 1 to 3-phase mains for phase sequence, overvoltage, and undervoltage. This makes it possible to react to neutral conductor interruptions and the overvoltages that typically occur in such cases, thus preventing consequential damage in electrical systems. The response time to mains faults is adjustable from 0.1s to 5s. After a fault condition, the relay can either switch on automatically or only after acknowledgment by an external button. Dimensions: 18x55mm, 230V AC - 1W pf 10A, Uvar 170-230V
