Product description

Intended use
The phase loss sensor is designed to protect the motor  power supply from a three-phase network in the event of a power failure in at least one phase or voltage asymmetry between the phases, threatening the destruction of the motor.Action
Power loss in at least one, any phase  or Voltage unbalance [V] between the phases above the activation threshold will cause the motor to be switched off. The switch-off will take place with a delay of 4 seconds, which prevents accidental disconnection of the motor in the event of a momentary voltage drop. Reactivation will occur automatically when  voltage increase by 5V above the operating voltage  (i.e. the value of the voltage hysteresis). With the above anomalies, the engine cannot be started.
