Siemens Mains Voltage Monitoring Relays
- Siemens 3UG4513-1BR20, This relay functions as a mains voltage monitoring relay, helping to provide optimum protection for machinery & equipment from a variety of electrical faults. The relay can be used without auxiliary voltage within the measured voltage range worldwide thanks to a wide voltage range. Typical applications include mobile equipment, e.g. air conditioning compressors, refrigerating containers, building site compressors & cranes, etc. This relay monitors undervoltage, phase sequence recognition, phase failure detection, phase unbalance, undervoltage detection 3-phase.
