The Schneider Electric RM22TA33 is a modular 3-phase asymmetry control relay designed for comprehensive electrical value monitoring within industrial and building automation control panels. This relay is part of the RM22 series, engineered for reliable performance in demanding environments. Its compact 22.5mm width allows for efficient space utilization on standard DIN rails, occupying the same footprint as a single-pole DIN device.

Technical details

• Series: RM22
• Functionality: 3-Phase Asymmetry Control Relay
• Monitoring Capabilities: Monitors electrical values in 3-phase systems. Specific parameters monitored include phase loss, phase sequence, and voltage asymmetry.
• Form Factor: Modular, 22.5mm width for DIN rail mounting.
• Voltage Rating: Designed for 3-phase industrial power systems. Specific voltage class requires datasheet verification.
• Output Contacts: Typically features relay outputs for control signaling. Exact contact configuration (e.g., SPDT, DPDT) and rating requires datasheet verification.
• Reset Type: Manual or automatic reset functionality may be available, requiring datasheet confirmation.
• Indicators: Integrated LEDs for status indication (e.g., power, fault).

Applications & compatibility

This RM22TA33 relay is commonly deployed in applications requiring robust 3-phase power monitoring and protection. It is suitable for use in motor control circuits, pump control systems, HVAC equipment, and general industrial machinery where maintaining balanced phase conditions is critical for operational integrity and equipment longevity.
