Network monitoring relay with phase sequence monitoring. 2 potential-free changeover contacts 10A/250V AC. 230V LED lamps up to 200W, incandescent lamps 2000W. Standby loss only 0.8 watts. Rail-mounted device for installation on a mounting rail (2 TE). For monitoring 230V AC voltage between 1 to 3 phase conductors and the neutral conductor, as well as for monitoring the phase sequence (clockwise) in the switch positions 2Ph and 3Ph. In the position L1/L2/L3, only the phase sequence is monitored, regardless of the mains voltage. If L1 fails, the relay drops out immediately without a drop-out delay. The lower rotary switch on the front allows for the setting of two pick-up and drop-out voltages, as well as the number of monitored phase conductors. 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 blinks quickly. Drop-out delay RV adjustable with the upper rotary switch from 0.1 to 8 seconds. While the RV time is running, the LED blinks slowly. Pick-up delay 0.5 s.
