CONTROL RELAY NR12-002-3X230V

Designed to monitor between 230V AC, one to three phase conductors and neutral, and to monitor rotation direction (clockwise) in the lower rotary switch positions 2Ph and 3Ph. Two different trip voltage levels selectable: 161V and 196V. De-energization delay adjustable between 0.1 and 8 seconds. Operating voltage L1-N 180-250V/50 Hz. If a fault occurs on L1, the relay immediately disconnects the power. The lower rotary switch allows selection of the on and off voltage levels and the number of phase conductors to be monitored. U1: 161V trip voltage and 185V energization voltage. U2: 196V trip voltage and 206V energization voltage. Complies with standard VDE 0100 part 718 (previously: VDE 0108, part 1). Voltage is indicated by an LED indicator. In case of incorrect phase sequence or phase failure, the LED flashes rapidly. The de-energization delay RV is adjustable via the upper rotary switch between 0.1 and 8 seconds. The LED flashes slowly during the de-energization delay. Start-up delay: 0.5 seconds. Maximum fuse: 16A. Modular unit for rail mounting according to standard DIN-EN 60715 TH35. 2 modules = width 36mm, depth 58mm. 230V LED load up to 200W. Incandescent lamp load up to 2000W. Standby power consumption only 0.8 watts. Also available with only one CO contact: NR12-001-3X230V (Part No. 27 018 49).
