Rectangular grey industrial relay, DIN-rail mount, twelve front pins, Macromatic PMD575 label

Macromatic

Macromatic PMD575 phase monitor relay 12 pins 480-600VAC electrical box

SKU CH-JWGN-YNG5D

Monitors three-phase voltage for overvoltage, undervoltage, phase loss, reversal and unbalance at 480-600 VAC with 12-pin DIN-rail mounting and auto or manual restart delay up to 300 seconds

  • TypeIndustrial Electrical Controls & Automation
  • Monitors overvoltage, phase loss, reversal, unbalance and undervoltage for comprehensive protection
  • Auto and manual restart with adjustable 1 to 300 sec delay for flexible recovery
  • DPDT contacts rated 10 A at 277 V AC and 30 V DC for reliable switching
  • DIN-rail mountable enclosure measuring 2.1 x 3.5 x 2.4 in fits standard panels
  • Operates on 480 to 600 V AC at 50/60 Hz for industrial power systems

Product Purpose

The Macromatic PMD575 is a phase monitor relay designed for industrial electrical control and automation systems. It protects three-phase equipment by monitoring voltage conditions across a 480 to 600V AC input range. The unit mounts on a DIN rail inside an electrical enclosure.

Protection Functions

This relay replaces basic voltage monitoring that only checks a single parameter. It continuously monitors for overvoltage, undervoltage, phase loss, phase reversal and phase unbalance. The jump is worthwhile when equipment damage or process downtime from any of these faults carries a high cost.

Target Applications

It suits maintenance engineers and panel builders who need automatic or manual restart control with a 1 to 300 second delay timer. The DPDT contacts rated at 10 A handle control circuits directly. Buyers who need monitoring for single-phase supplies or voltages outside the 480 to 600V AC range should look at alternative devices.

Highlights

  • Monitors overvoltage, phase loss, reversal, unbalance and undervoltage for comprehensive protection
  • Auto and manual restart with adjustable 1 to 300 sec delay for flexible recovery
  • DPDT contacts rated 10 A at 277 V AC and 30 V DC for reliable switching
  • DIN-rail mountable enclosure measuring 2.1 x 3.5 x 2.4 in fits standard panels
  • Operates on 480 to 600 V AC at 50/60 Hz for industrial power systems

Questions about this item

What DIN rail width does the 2.4 in deep Macromatic PMD575 relay clip onto?

The relay mounts on a standard DIN rail; the body measures 2.4 in deep, 3.5 in high and 2.1 in wide.

Which step is often missed when wiring the 12 pins for 480-600V AC monitoring?

Insert each of the 12 pins into the matching socket terminals and verify the DPDT contact wiring before applying 480-600V AC power.

When should the DPDT contacts be replaced after 10 A at 277V AC switching?

The electrical operating durability is rated at 100,000 cycles; plan contact replacement once that count is reached.
