The Eaton EMR6-PH22 is a ground fault relay designed to provide overvoltage, undervoltage, and phase loss protection for three-phase electrical systems. It monitors and protects line-to-ground and line-to-line voltages, and can detect low voltage, high voltage, voltage unbalance, phase sequence, and phase loss. The EMR6-PH22 has adjustable voltage settings and an onboard LED for easy indication of status. It also includes an automatic reset capability which ensures the system is immediately available in the event of a fault. This relay is UL and RoHS certified and has a wide range of applications such as motor control, manufacturing operations, and power monitoring.
