3-Phase sequence and loss monitoring relays
Product Description
Since it very seldom happens that there is human surveillance of pumps, minor failures may occur as incorrect phase sequence cause major problems such as flooding. The DPA01, PPA01 and DPA51 detect for the correct phase sequence and phase loss along with the voltage regenerated by the pumps motor; this means that the maintenance department can easily and promptly be notified before a system failure occurs.
