2 changeover contacts, potential-free 10A/250V AC. 230V LED lamps up to 200W, incandescent lamps 2000W. Standby loss only 0.8 watts. Modular device for mounting on DIN-EN 60715 TH35 rail. 2 division units = 36mm wide, 58mm deep. For monitoring 230V AC voltage between 1 to 3 external conductors and the neutral conductor and for monitoring the rotating field (clockwise) in the rotary switch positions 2 Ph and 3 Ph. In the L1/L2/L3 position, only the rotating field is monitored, regardless of the mains voltage. Supply voltage L1-N 180-250V/50Hz. If L1 fails, the relay drops out immediately without a release delay. Two pull-in and pull-out voltages can be set using the lower rotary switch on the front and the number of monitored outer conductors must be specified. U1: 161V pull-out voltage and 185V pull-in voltage, U2: 196V pull-out voltage and 206V pull-in voltage in accordance with 0100, Part 718 (previously: 0108, Part 1). LED display for correct voltage applied. If the polarity is incorrect or an outer conductor is missing, the LED flashes quickly. Pull-out delay RV can be set from 0.1 to 8 seconds using the upper rotary switch. While the RV time is running, the LED flashes slowly. Pull-in delay 0.5s. Maximum device fuse 16A.
