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 phase sequence recognition.
