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.
Phase monitoring relay for mains monitoring, detecting phase sequence, failure, asymmetry, and over/under voltage issues in 183-528V systems.
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.
