Mains monitoring relay with rotating field monitoring. 2 changeover contacts potential-free 10A/250V AC. 230V LED lamps up to 200W, incandescent lamps2000W. Stand-by loss only 0.8 Watt. Modular device for mounting on mounting rail (2 TE). For monitoring 230V AC voltage between 1 to 3 phase conductors and the neutral conductor and for monitoring the rotating field (clockwise) in rotary switch positions 2Ph and 3Ph. In position L1/L2/L3 only the rotating field is monitored, independent of the mains voltage. If L1 fails, the relay drops out immediately without a release delay. Two pick-up or drop-out voltages can be set with the lower rotary switch on the front panel and the number of monitored phase conductors must be specified. U1: 161V drop-out voltage and 185V pick-up voltage. U2: 196V drop-out voltage and 206V pick-up voltage according to VDE 0100, part 718 (formerly: VDE 0108, part 1). LED display for correct applied voltage. In case of incorrect polarity or a missing phase conductor, the LED flashes quickly. Release delay RV adjustable from 0.1 to 8 seconds with the upper rotary switch. While the RV time is running, the LED flashes slowly. Pick-up delay 0.5s.
