RS PRO Phase Monitoring Relay, 3 Phase, DIN Rail, Surface Mount

RS PRO Phase Sequence/Failure Indicator

RS PRO is proud to introduce this high-quality monitoring relay. This device is a 3-Phase indicator used for monitoring a 3-wire supply while providing a visual indication as to the status of the phase sequence/rotation and presence of all phases.

The monitor has one bi-colour LED used to indicate phase rotation and illuminates in green to confirm the sequence is correct. If the rotation is incorrect the LED changes to red. Three individual green LEDs are incorporated to indicate the status of each phase i.e. L1, L2, and L3.

Where would you find a monitoring relay?

Monitoring relays are commonly found in control panels, switchboards, or distribution systems that require visual indication and status of a 3-phase power supply.
