This relay functions as a mains voltage monitoring relay, helping to provide optimum protection for machinery and 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 and cranes, etc.
This relay monitors undervoltage, phase sequence recognition, phase failure detection, phase unbalance, undervoltage detection 3-phase.
- LED display for status
- Auto reset
- Removable terminals
