Macromatic's PMPU three-phase monitor relay offers several advantages, including a wider line-line voltage range, adjustable undervoltage setting, the ability to keep checking the voltage even if a phase is lost and to be manually reset via an external switch, dedicated fault indication, and RoHS compliance. This chart compares the features of Macromatic along with those of similar relays.
