Product description

Intended use
The phase sequence and loss sensor is designed to protect electric motors powered from a three-phase network in the event of a voltage loss in at least one phase or voltage asymmetry between phases, threatening the destruction of the motor, and protection of the direction of motor rotation in the event of a phase change in front of the sensor.
Action
Voltage failure 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 the set delay, 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, starting the engine is impossible. In the event of a change in the sequence of phases before the sensor, causing an undesirable change in the direction of rotation of the motor, the sensor will not allow the motor to start. Reactivation is possible after the return of the correct phase sequence.
