Phoenix Contact EMD-FL-3V-500 – Monitoring Relay for 3-Phase Voltages 350–650 V AC, Undervoltage/Overvoltage, Phase Failure, Asymmetry, Wide Power Supply Range, 2 Changeover Contacts (Item 2867979)

Phoenix Contact EMD-FL-3V-500 — 3-Phase Voltage Monitoring Relay

The EMD-FL-3V-500 is a Phoenix Contact compact monitoring relay for 3-phase systems with a wide monitoring voltage range of 350–650 V AC. It detects undervoltage, overvoltage, phase failure, and phase asymmetry — protecting motors, drives, and equipment from the most common causes of 3-phase supply faults. The supply voltage can be selected via a module, and the unit provides 2 changeover contact outputs for alarm or trip functions.
