Sequencer controller Schneider

Monitors three‑phase power for correct sequence, phase loss, and voltage asymmetry up to 576 V AC. Compact DIN‑rail design with low power consumption delivers instant alarm outputs for reliable protection and efficient energy management.

The Schneider Electric RM22TU23 is a voltage monitoring relay that provides mains monitoring for phase sequence, failure and undervoltage. It ensures the safety and reliability of electrical systems by detecting any abnormalities in the power supply.
