8430 phase failure relays offer the reliability and accuracy of solid state circuitry with the isolation of hard output
contacts.
Phase Abnormality Definitions
Phase Loss: This condition occurs when one line of a 3 phase system is completely lost.
Phase Unbalance: This condition occurs when the voltage in one line of a 3 phase system drops below the voltage in
the remaining two lines.
Phase Reversal: This condition occurs when two of three lines in a 3 phase system are switched. This incorrect
connection will cause a motor to rotate in the reverse direction.
Undervoltage: This condition occurs when the voltage in all three lines of a 3 phase system drop simultaneously.

Phase Failure and Undervoltage Relay
The Type MPS is a socket mounted, voltage sensing phase failure relay. The
undervoltage setting is adjustable from 75% to 100% of normal voltage. The
relay is UL Listed with the appropriate socket (see socket selection on
page 23-13). The 240 V rated, SPDT output contacts change state upon
phase failure, undervoltage, phase reversal or phase unbalance of 10% or
greater. Response time delay is 3 seconds.
Phase Failure and Undervoltage Relay
The Type MPD offers the same protection as the Type MPS plus the
following features: DPDT 600 V rated output contacts, locking potentiometer
undervoltage adjustment and an LED indicating “relay energized.” Can be
mounted directly to a panel or to 8501 XM track (see page 23-23).
