Overview

SSAC

Protection Relays, PLR Series

Item# PLR480A - Voltage Monitor, 3-Ph, Phase Loss, Phase Reversal, Undervoltage, Phase Unbalance, 380-500VAC

PLR Series Information
  • Protects against phase loss (on startup), phase reversal & undervoltage
  • Used where moderate voltage unbalance protection is not required
  • Direct replacement for most popular 3‑phase monitors
  • 8-pin octal base connection
  • Isolated, 5A, SPDT output contacts
The PLR Series provides a cost effective means of preventing 3‑phase motor startup during adverse voltage conditions. Proper A‑B‑C sequence must occur in order for the PLR’s output contacts to energize. In addition, the relay will not energize when an undervoltage or phase loss condition is present. The PLR protects a motor against undervoltage operation. The adjustment knob sets the undervoltage trip point.
