The PMP Series Phase Monitor Relays utilize a microprocessor-based design to provide
protection against phase loss, phase reversal, phase unbalance, undervoltage and
overvoltage. The PMPU is a universal voltage product that works on any three-phase
system voltage from 208-480V (a separate 120V version is available). These devices are
designed to be compatible with most Wye or Delta systems. In Wye systems, a connec-
tion to a neutral is not required. PMP Series products protect against unbalanced voltages
or single phasing regardless of any regenerative voltages.
The relay is energized when the phase sequence and all voltages are correct. Any one of
five fault conditions will de-energize the relay. As standard, re-energization is automatic
upon correction of the fault condition. Manual reset is available if a momentary N.C.
switch is wired to the appropriate terminals. A multi-color LED indicates normal condition
and also provides specific fault indication to simplify troubleshooting.
The PMP Series offers a variety of user-adjustable settings. The percent phase unbalance
is adjustable from 2-10%, and also has a “Disable” setting for those applications where
poor voltage conditions could cause nuisance tripping. The undervoltage drop-out can be
set at 80-95% of operating voltage (overvoltage setting is fixed at 110% of nominal). The
adjustable time delay drop-out on undervoltage (0.1-20 seconds) eliminates nuisance
tripping caused by momentary voltage fluctuations. There is also an adjustable time delay
(1-300 seconds) on both power up and restart after a fault has been cleared.
Requires a 600V-rated socket when used on system voltages greater than 300V.
