  • Voltage Unbalance : Refers to a voltage imbalance that will affect the of the device. When the voltage imbalance rate is higher than 8%. The form of the indicator light is: the lack of phase red light is on, and priority.Three-phase voltage imbalance , static phase loss , reverse phase , , and .
  • Dynamic Phase Loss, Static Phase Loss : Refers to the phase failure of any phase when the protected device is in the running state or non-operating state. The indicator light is in the form of red light and priority.There is no requirement for motor wiring when used for motor .
  • The function of the monitor is not affected by the current of the line or load, the inrush current, the unbalanced current and the nature of the load. Long-term work with full performance and full climate. Power consumption is no more than 2W.
  • Delay : When there is a fault, the monitor will delay after 1~2 seconds, and the relay will release.
  • Wrong Phase : A measure to prevent the phase sequence of L1, L2, L3 three-phase AC power supply from being connected incorrectly. Instant action. The indicator light is in the form of yellow light.This product complies with GB/T 14048.1-2000, GB14048.5-2001 eqv IEC60947-1:1999.


Product Description

B07SDGQ4ZN+GS16471

Working status:

  • 1. L1, L2, L3 three-phase wiring is correct, the monitor green light is on, the relay is closed; if the phase sequence is wrong, the monitor yellow light is on, just exchange any two phases of L1, L2, L3 three phases, the monitor will Can recognize the phase sequence and work normally.
  • When the protected device is working normally, the yellow light is on, and when the relay does not pick up, it should be regarded as misconnection of the external line phase sequence, and the monitor has the function of preventing misconnection protection;
  • 2. When the L1, L2, and L3 phases are out of phase, the red light is on, the green light is off, and the relay is released; when the voltage is normal, the green light is on and the relay is closed;
  • 3. L1, L2, L3 are connected to three-phase AC voltage, NO and COM are normally open contacts; NC and COM are normally closed contacts. Use wire to connect the terminal block directly.​
