RM22TR33 Multifunction 3-Phase Voltage Monitoring Relay
Core Functions: Comprehensive three-phase monitoring—including phase sequence, phase loss, over-voltage, under-voltage, and three-phase voltage imbalance—with adjustable time-delay functionality.
Terminal Definitions
L1/L2/L3: Three-phase 380V input;
A1/A2: Auxiliary power supply;
16/18: Fault alarm contacts.
Practical Applications
1. Includes all phase sequence and phase loss protection features found in the RM22TG20;
2. Provides time-delayed shutdown protection in cases of high grid voltage (over-voltage), low grid voltage (under-voltage), or excessive voltage difference between phases;
3. Suitable for precision equipment—such as elevators, injection molding machines, central air conditioning systems, and large air compressors—where high voltage stability is required.
