Phoenix Contact MR-ES-Ph-400 – Monitoring Relay for 3-Phase Voltages 400 V AC, Undervoltage/Overvoltage, Phase Failure, Phase Sequence, 1 Changeover Contact, Screw Connection (Item 1217806)

Phoenix Contact MR-ES-Ph-400 — 3-Phase Monitoring Relay

The MR-ES-Ph-400 is a Phoenix Contact monitoring relay designed to protect 3-phase electrical systems operating at 400 V AC. It continuously monitors for undervoltage, overvoltage, phase failure, and phase sequence errors — the most common causes of motor and equipment damage in three-phase installations. With a single changeover contact output and screw connection terminals, it integrates easily into any control panel.
