⚡ RM22 1‑Phase Voltage Relay

The RM22 1‑phase voltage relay from Schneider Electric is a compact, DIN‑rail‑mounted device designed to monitor single‑phase voltage conditions and protect equipment from electrical faults. It supervises key parameters such as overvoltage, undervoltage, voltage asymmetry, and supply stability, depending on the model.

🔧 Key Features

• Single‑phase voltage monitoring — Detects overvoltage, undervoltage, and supply irregularities.
• Adjustable thresholds — Set trip levels and time delays to match application needs.
• Relay output — Activates alarms, shutdowns, or control actions when faults occur.
• LED indicators — Provide quick visual status for power, faults, and relay state.
• Compact DIN‑rail design — Slim housing for easy installation in control panels.
• Wide supply voltage compatibility — Suitable for various single‑phase systems.

🏭 Typical Applications

• Single‑phase motor protection
• Pumps, fans, HVAC units
• Control panels and distribution boards
• Automation equipment supply monitoring
