Single Phase Relay for Motor Protection.

The Over/Under Voltage Monitor is used to protect single phase equipment that is required to operate between two voltage limits. In a normal voltage environment, the internal relay of the Single Phase Monitor will energize and the LED will illuminate allowing normal operation. Abnormal voltage conditions will cause the internal relay of the Voltage Monitoring Relay to de-energize and the LED to turn off. These Voltage Sensor Relays are available in 8 or 12 pin configurations.
