Schneider Harmony RM22 Series Monitoring Relays

Schneider Harmony RM22 Series Monitoring Relays Suppliers, Exporters in India

Schneider Harmony RM22 Series Monitoring Relays are multifunction electronic relays designed to continuously monitor critical electrical parameters in industrial power and control systems. They help protect equipment by detecting abnormal conditions such as phase failure, phase sequence reversal, overvoltage, undervoltage, overcurrent, undercurrent, and liquid level variations, depending on the model.

The RM22 Series is built for applications where reliable monitoring is essential for maintaining process continuity and protecting motors, pumps, compressors, and other electrical equipment. With adjustable settings and clear LED status indication, these relays allow users to configure monitoring thresholds according to the application while making fault diagnosis straightforward.

Designed for DIN rail mounting, Harmony RM22 relays fit easily into new control panels as well as retrofit installations. Their compact construction, dependable performance, and wide range of monitoring functions make them suitable for industrial automation, building services, water treatment, and machine control applications.
