EMR4-F500-2

The EMR4-F500-2 from Eaton is a 2W phase sequence relay. It monitors three phase systems for phase sequence and phase failure (< 0.6 x Ue). This phase sequence relay is required for various applications in electrical switchgear technology. It complies with IEC 255-6 and EN 60255-6 standard. The EMR4-F500-2 phase sequence relay with its compact 22.5mm width is used for monitoring the clockwise rotation of movable motors for which the phase sequence is important such as with pumps, saws and drilling machines. A clockwise phase sequence causes the changeover contact to enable the control voltage for the motor switchgear.
