Mains monitoring relay with phase sequence monitoring. Standby power consumption only 0.8 watts. DIN rail mounting device (1 TE). For monitoring 230V AC voltage between 1 to 3 live conductors and the neutral conductor, and for monitoring the phase sequence (clockwise) in the 2Ph and 3Ph rotary switch positions. In the L1/L2/L3 position, only the phase sequence is monitored, regardless of the mains voltage. Supply voltage L1-N 180-250V/50Hz. If L1 fails, the relay drops out immediately without any delay. The lower rotary switch on the front panel allows you to set two pull-in and pull-out voltages, and the number of monitored live conductors must be specified. U1: 161V pull-out voltage and 185V pull-in voltage. U2: 196V pull-out voltage and 206V pull-in voltage according to VDE 0100, Part 718 (formerly: VDE 0108, Part 1). LED indicator for correct voltage application. The LED flashes rapidly if the polarity is incorrect or a live conductor is missing. The pull-out delay (RV) is adjustable from 0.1 to 8 seconds using the upper rotary switch. The LED flashes slowly while the RV time is running. Pull-in delay: 0.5s. Maximum device fuse rating: 16A.
