MULTISPAN VOLTAGE & CURRENT PROTECTION RELAY – PANEL MOUNTED VMR-23

The VMR-23 Multispan is a compact and highly reliable voltage monitoring relay designed to protect electrical systems and equipment from abnormal voltage and frequency conditions.  The VMR-23 continuously monitors three-phase and single-phase power networks to detect faults such as over voltage, under voltage, over frequency, under frequency, phase loss, phase sequence reversal, and voltage asymmetry. The relay is suitable for 3Ø-3W, 3Ø-4W, and 1Ø-2W electrical systems, making it ideal for industrial panels, generators, motors, transformers, and automation applications.
