Description
 

The Macromatic PMP575 is a three phase monitor electrical relay that monitors for several different types of phase errors. This 8 pin plug in relay has an adjustable nominal voltage of 460-600V, with an output of 10A SPDT. The LED on top will be green if everything is functioning correctly. If the relay finds an error, the LED glows or blinks red. The diagram on top of the unit shows how the LED will indicate the current status. The PMP575 uses an 8 pin 70169-D octal socket. Note: Image is an approximation. Actual part may differ.

Monitors For:
Phase Reversal
Phase Loss
Phase Unbalance
Overvoltage
Undervoltage

Specifications

  • Relay Function- Three Phase

  • Minimum Voltage- 345 V
  • Maximum Voltage- 660 V
  • Power Consumption- < 40VA
  • Output- 10A SPDT
  • Phase Reversal- Trips if rotation is something other than A-B-C

Additional Product Information

Like other phase monitor relays, the PMP575 utilizes "True RMS voltage measurement". Analog to digital sensing circuitry in True RMS voltage measurement allows the relay to be more precise in monitoring phases and voltages. One useful feature is that even if a phase is lost, it can still monitor all the voltages while indicating the fault. It is important that this relay be used with a 600V rated socket if the system voltage is above 300V. These relays are ideal for heavy duty applications, such as in the mining or petrochemical industries. 575V applications can often be found in Canada as well. The unit energizes after a Restart Delay when voltage is introduced, as long as the phases stay in the right order. If a phase error is detected, it de-energizes after a delay. Once the error is fixed, it will energize again on its own. It is possible to have a manual reset if an external momentary N.C. switch is attached to pins 6 and 7.
