Protection Relays, PLM Series
Item #
PLM6805
Voltage Monitor, 240V, 3 Phase,

PLM Series Information

  • Protects against phase loss & reversal; & under & unbalanced voltages
  • 8‑pin plug‑in base
  • Adjustable low voltage trip point
  • Factory fixed unbalance & trip delay
  • Line voltages 200 to 480VAC in 3 ranges
  • Isolated, 10A, SPDT output contacts
The PLM Series continuously measures the voltage of each of the three phases. The PLM Series uses a microcontroller circuit design that senses undervoltage, voltage unbalance, phase loss, and phase reversal. Protection is assured when regenerated voltages are present. Both delta and wye systems can be monitored; no connection to neutral is required.
