Features
  • The 3UG4511-1BP20 is an analogue phase sequenced Monitoring Relay, the phase sequence in a three-phase network and no adjustments are required for operation

  • The device has an internal power supply and works using the closed-circuit principle

  • If the phase sequence at the terminals L1-L2-L3 is correct, the output relay picks up after the delay time has elapsed and the LED is lit. If the phase sequence is wrong, the output relay remains in its rest position

  • Analogue Phase Sequence Monitoring Relay

  • SPST-NC Contact Configuration

  • Variably Adjustable to Overshoot, Undershoot or Range Monitoring

  • Freely Configurable Delay Times and Reset Response

  • Provides Maximum Protection for Mobile Machines and Plants or for Unstable Networks

  • Automatic direction correction of rotation by sensing power system faults and wrong phase sequence


Applications
  • HVAC, Portable Devices, Building Automation
