RS PRO RS PRO 17.5mm Monitoring Relay

RS PRO Phase Sequence/Fault Indicator. RS PRO is proud to bring you this high quality monitoring relay.
This device is a 3 phase indicator used to monitor 3 wire power supplies and provides a visual indication of phase sequence/rotation status and the presence of all phases.
The monitor has one bi-color LED that is used to indicate phase rotation and lights green to confirm the sequence is correct.
If the rotation is incorrect, the LED will turn red.
It incorporates three green LEDs to indicate the status of each phase (L1, L2, L3).
