"Monitoring of rotating field, 1 changeover contact, modular device for rail mountingDesigned 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.
On-delay: 0.5 secondsStand-by loss only 0.8 W"
