Eaton EMR6-AW500-D-1 Phase Monitor Relay 3x200-500V AC, 2 CO, DIN Rail 184764

Monitor 3-phase networks from 200 to 500 V AC with the Eaton EMR6-AW500-D-1. This self-supplied phase monitor detects phase sequence, phase failure, overvoltage, undervoltage, and asymmetry, with adjustable response and switch-on delays up to 30 seconds.

Overview

The EMR6-AW500-D-1 is a compact monitoring relay for three-phase systems. It operates across a wide voltage range (3x 200–500 V AC) at 50/60 Hz, powered directly from the measured voltage—no auxiliary supply needed. Two change-over contacts provide flexible output switching.

What stands out

• Adjustable overvoltage, undervoltage, and asymmetry thresholds
• Separate response delay (t1) and switch-on delay (t2) from 0.1 to 30 s
• LED indicators for status, relay state, and error conditions
• DIN rail mounting, 22.5 mm width (1 module)
• Operating temperature from -25 to +60 °C
