Phase sequence and phase loss sensor CKF-316 10A 1P CKF-316 F&F

Product description

Voltage loss in at least one phase of any kind or voltage asymmetry between phases above the tripping threshold will cause the motor to shut down. Shutdown will occur with a delay of 4 s, which prevents accidental disconnection of the motor during a temporary voltage drop. Reconnection will occur automatically when the voltage rises by 5 V above the trip voltage (i.e., by the voltage hysteresis value). With the above anomalies, it is impossible to start the motor. In the case of a change in the order of the phases in front of the sensor causing an undesirable change in the direction of rotation of the motor, the sensor will not allow the motor to start. Reconnection is possible after the return of the correct phase order.
