SIEMENS 3UG45111BP20 Phase Monitoring Relay
The 3UG4511-1BP20 is an analogue phase sequence monitoring relay designed to verify the correct phase sequence in three-phase networks without adjustments. It features an internal power supply, LED indicator, and a SPST-NC contact configuration. The relay activates when the phase sequence at L1-L2-L3 is correct, after a preset delay, and remains inactive if incorrect. It offers adjustable delay times, automatic correction of rotation direction, and maximum protection for industrial applications, HVAC systems, and building automation, ensuring reliable phase monitoring and system safeguarding.
