Macromatic Phase Monitor Relay, 190 to 500V AC, 10A @ 277V, 7A @ 30V, 8 Pins, SPDT

Macromatic's PCP Series Three-Phase Monitor Relay continuously monitors all voltages of a 190-500V three-phase system. It is used to protect motors and equipment from expensive damage due to phase reversal only. This relay has an isolated relay output that is only energized if the three phases are in the proper A-B-C sequence. The relay output will remain open if any two phases are reversed. One version will work on any three-phase system from 190-500V. No adjustment or special set up is required. Designed to be compatible with most Wye or Delta systems with no connection to Neutral required. Phase Reversal Relay should be used in applications where motor direction is critical or sequence detection is required by code.
