EMR4-F500-2 Phase SequenceRelay – Phase Sequence Monitoring with a Compact Device
The EMR4-F500-2 phase sequence relay with its compact 22.5 mm width is used for monitoring the clockwise rotation of movable motors for which the phase sequence is important, such as with pumps, saws, drilling machines. Benefits: Additional space in the control panel thanks to the narrow width Protection against damage by means of phase sequence monitoring
A clockwise phase sequence causes the changeover contact to enable the control voltage for the motor switchgear. The EMR4-F500-2 covers the entire voltage range from 200 V AC to 500 V AC.
