Schneider Electric Monitoring Relay 1 Phase DPDT, DIN Rail, 110 - 240V AC, 8A, Harmony Control RM22UB34

Schneider Electric RM22UB34 Monitoring Relay is a specialized electrical device engineered for voltage monitoring in 1-phase systems. It belongs to the Harmony Control series and is suitable for industrial automation, panel protection, and sensitive equipment safeguarding. This relay continuously supervises supply voltage and triggers DPDT changeover contacts if an overvoltage or undervoltage condition is detected, preventing potential damage or operational interruptions.

The RM22UB34 supports supply voltages ranging from 110V to 240V AC, allowing flexible use across various installations. Its integrated adjustable time delay, optimizable between 0.1 and 30 seconds, provides precision in response timing for voltage anomalies. The DPDT contact configuration supports multiple circuit arrangements, and the relay handles load currents up to 8A AC, meeting common requirements in automated control and electrical protection systems.

Installation is straightforward via DIN rail mounting, minimizing panel space and simplifying integration. Screw terminals are compatible with solid or flexible cables, making wiring practical and expedient. With enclosure protection rated at IP20, IP40, and IP50, the unit offers resistance against dust and accidental touch, supporting operational safety and reliability. The wide operating temperature spans from -20°C to +60°C, ensuring stable performance in indoor environments.

Overvoltage and undervoltage conditions are actively monitored, with timely alerts to help protect connected systems. The relay adheres to international standards including RoHS, IEC 60068-2-30, IEC 60255-27, REACH, IEC 60068-2-27, and IEC 60068-2-6, making it suitable for use in demanding industrial environments.

Typical applications for the Schneider Electric RM22UB34 include industrial automation control panels, electrical installations requiring voltage detection, and protection of sensitive machinery from voltage fluctuations. Its robust construction and high reliability make it an essential component for industrial, commercial, and process applications.
