NR12-001-3X230V Mains monitoring relay - 1 changeover contact, 250 V/10 A

Monitoring of rotating field, 1 changeover contact, modular device for rail mounting

Designed to monitor 230 V AC voltage between the single-phase conductor, the external conductor and the neutral conductor, and to monitor the rotating field (clockwise) in the rotary switch positions of the double-phase and triple-phase conductors. LED display for correctly applied voltage. The LED flashes rapidly in the case of wrong polarity or a missing external conductor. Release delay can be set from 0.1 to 8 seconds.
