| Item Description | Mains monitoring relays 3X230V. 2 CO contacts potential free 10A/250V AC / mains monitoring relays monitoring the rotating field. Standby loss 0.8 watt only. Modular device for DIN 60715 TH35 rail mounting. 1 module =18MM wide, 58MM deep. Designed to monitor 230V AC voltage between 1 to 3 phase conductors and neutral and to monitor the rotating field (clockwise) in the switch positions 2PH and 3PH. In the position L1/L2/L3 only the rotating field is monitored, independent from the mains voltage. Supply voltage L1-N 180-250V/50HZ. In case of failure of L1 the relay releases immediately without delay. With the lower rotary switch on the front two operate voltages resp. Dropout voltages CAN be set and the number of monitored phase conductors must be selected. U1: 161V dropout voltage and 185V operate voltage. U2: 196V dropout voltage and 206V operate voltage as per VDE 0100, part 718 (forme |
