SIEMENS 3UG45111BP20 Datasheet & Stock
The 3UG4511-1BP20 is an analogue phase sequence monitoring relay designed to verify the correct phase sequence in a three-phase network without the need for adjustments. It features an internal power supply and operates on a closed-circuit principle. When the phase sequence at terminals L1-L2-L3 is correct, the relay activates after a preset delay and an LED indicator lights up. If the phase sequence is incorrect, the relay remains in its resting state. The relay has SPST-NC contact configuration, with adjustable settings for overshoot, undershoot, or range monitoring. It allows for variable delay times and reset response, providing maximum protection for mobile machines, plants, or unstable networks. Additionally, it can automatically correct the rotation direction by sensing power system faults or incorrect phase sequence. Suitable for HVAC systems, portable devices, and building automation.
