Mains monitoring relay with phase sequence monitoring. Standby power consumption only 0.8 watts. DIN rail mounting device (2 modules). For monitoring 230V AC voltage between 1 to 3 phase 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. If L1 fails, the relay drops out immediately without any delay. The lower rotary switch on the front allows you to set two pull-in and drop-out voltages, and you must specify the number of phase conductors to be monitored. U1: 161V dropout voltage and 185V pull-in voltage. U2: 196V dropout voltage and 206V pull-in voltage according to VDE 0100, Part 718 (formerly: VDE 0108, Part 1). LED indicator for correct voltage applied. The LED flashes rapidly if the polarity is incorrect or a live conductor is missing. Dropout 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: 0.5 seconds.
