3-Phase Pump Protection Relay P19 by undercurrent 4-10hp 115V aux volt (Discontinued)

Fanox Three-Phase Pump Protection Relay P19 uses the motor itself as a sensor, therefore, does not require an external detector, such as level electrodes, to detect dry-running. It monitors the load of the motor and stops it before an expensive breakdown occurs. For example, when a water well is dry, the relay stops the motor by undercurrent without the need of a level sensor.
Features
