Schneider RM22TG20 3-Phase Monitoring Relay, RM22TR33 Phase Loss/Over/Under Voltage, RM22LG11MR Liquid Level Control Relay, 208-480VAC

Product Description


The Schneider RM17/RM22 Series Harmony Control Relays are compact, DIN rail-mountable monitoring relays designed for industrial power system protection and control. These relays provide reliable monitoring of 3-phase voltage, phase sequence, phase loss, over/under voltage, and liquid levels, ensuring stable operation of motors, pumps, and other critical equipment.

Core Features by Model

Model Primary Functions Voltage Range Key Features
RM22TG20 3-phase monitoring (phase sequence, phase loss) 208-480V AC Simple, cost-effective phase monitoring, 2CO 8A contacts
RM22TR33 3-phase phase loss, over/under voltage monitoring 380-480V AC Adjustable voltage thresholds, phase unbalance detection, 2CO 8A contacts
RM22LG11MR Liquid level control relay 24-240V AC/DC Universal voltage input, automatic level control for pumps/tanks
RM17TG00/RM17TG20 3-phase monitoring (phase sequence, phase loss) 208-480V AC Compact design, basic phase protection for light-duty applications


 Common Features

  • DIN Rail Mounting: Compact form factor (RM22 series) and ultra-compact design (RM17 series) for easy installation in control cabinets.
  • Adjustable Settings: Most models include potentiometers for setting voltage thresholds, unbalance levels, and time delays (0.1-30s).
  • Status LEDs: Visual indication of power, output status, and fault conditions (phase loss, over/under voltage) for quick troubleshooting.
  • Diagnostic Button: Test function to simulate fault conditions and verify relay operation.
  • Wide Operating Range: Suitable for global industrial power grids, with models covering 200-480V AC and 24-240V AC/DC.

Applications

  • Motor phase sequence protection (prevent reverse rotation)
  • Phase loss and voltage anomaly protection for pumps, compressors, and industrial machinery
  • Liquid level control for water tanks, sewage systems, and chemical processing
  • Emergency power switching and power quality monitoring
