Product Details

Macromatic's PMP 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 loss, phase reversal, phase unbalance, undervoltage and overvoltage faults, as well as rapid cycling. This product detects single phasing and unbalanced voltages regardless of regenerative voltages. Unlike similar three-phase monitor relays, the PMP Series will continue to function even with a lost phase. They are the only line-powered units in their class to retain fault indication and continuous monitoring of all voltages during a phase loss, increasing the ease of troubleshooting and the level of protection.

Phase Monitor Relay, 190 to 500VAC Input Voltage, Contact Form: SPDT, Base Type: Octal is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from This Macromatic 3 Phase Line Monitor was very easy to install. replaced the no longer avaliable MPS8430 relay used in our Tower elevator controls. A quick change to the new 8 pin socket and we were up and running.More control settings than the old relay which I like.. Can't beat the price. Ken
