| Description | Phase Monitor Relay; 3-Phase; Self-powered (200...240 V AC) |
| Datasheet | Download Datasheet |
The Schneider Electric RM22TR31 is a 22.5 mm phase monitor relay with 2 Form C (DPDT) output and rated 8 A, 250 V AC max; 2000 VA, driven by a Self-powered (200 to 240 V AC) input.
It watches all three phases for phase sequence, phase failure detection, overvoltage and undervoltage detection, measuring true RMS (150 ms measurement cycle).
The undervoltage trip point is adjustable 2...20% of selected un.
It drops out 0.1...30 s adjustable after an undervoltage.
It has 35 mm DIN rail mounting and screw terminals.
