Three-phase network control relay series RM17 Tx00. Schneider Electric multifunctional three-phase power supply control relay of the RM17Tx00 series. Monitors the correct sequence of phases L1, L2, and L3 as well as the total failure of one or more phases. In the event of a phase sequence error or a missing phase, the relay opens immediately. In case of a voltage error, the relay opens at the end of the set delay time. Transparent front panel with hinges, potentiometer on the front side, LED output status, DIN rail. Phase, asymmetry, and undervoltage/overvoltage regulator: RM17 TE00. The relay monitors its own supply voltage Un: The relay checks the direct sequence of the three phases, the failure of at least one of the three phases (U measured; 0.7 x Un), asymmetry adjustable from 5 to 15 % of Un, over- and undervoltage drift in window mode adjustable from 2 to 20 % of Un.
