Mains monitoring relay 2W potential-free 10A/250V - Phase monitoring relay 230V NR12-002-3x230V

Mains monitoring relay 2W potential-free 10A/250V - Phase monitoring relay 230V NR12-002-3x230V – Eltako – 22002330 – 4010312202548: Mains monitoring relay 2W potential-free 10A/250V NR12-002-3x230V Design of the electrical connection screw connection, type of voltage for actuation AC, phase sequence monitoring function, phase failure detection function, undervoltage detection function, overvoltage detection function, voltage measuring range 230 ... 230V, min. adjustable off-delay time 0.1s , Max. permissible release delay time 8s, number of contacts as opener 0, number of contacts as closer 0, number of contacts as changeover contact 2, width 36mm, height 58mm, depth 58mm, mains monitoring relay with rotary field monitoring. Standby loss only 0.8 watts. Modular installation device for mounting on DIN rail (2 HP). For monitoring 230V AC voltage between 1 to 3 phase conductors and the neutral conductor and for monitoring the rotating field (clockwise) in the rotary switch positions 2Ph and 3Ph. In the L1/L2/L3 position, only the rotary field is monitored, regardless of the mains voltage. If L1 fails, the relay drops out immediately without an off-delay. With the lower rotary switch on the front, two pull-in and drop-out voltages can be set and the number of monitored phase conductors must be specified. U1: 161V release voltage and 185V pickup voltage. U2: 196V release voltage and 206V pick-up voltage according to VDE 0100, part 718 (formerly: VDE 0108, part 1). LED display for correct applied voltage. If the polarity is wrong or there is no phase conductor, the LED flashes quickly. OFF-delay RV adjustable from 0.1 to 8 seconds with the upper rotary switch. While the RV time is running, the LED flashes slowly. Pick-up delay 0.5s.
