Schneider Electric Phase, Voltage Monitoring Relay, 3 Phase, SPDT, 183 → 528V ac, DIN Rail

NF EN 60255-6 and IEC 60255-6. UL, CSA, GL, C-Tick, GOST. RM17 Tx00 Series Three-Phase Network Control Relay. Schneider Electric RM17Tx00 Series multi-function 3 phase supply control relays. Monitoring the correct sequencing of phases L1, L2, and L3 and the total loss of one or more of each phase. In the event of a phase sequence or missing phase fault, the relay opens instantly. In the event of voltage fault, the relay opens at the end of the time delay set. Clear hinged front cover Front face potentiometer LED output status DIN rail. Phase, Asymmetry and Under-Voltage / Over-Voltage Controller: RM17 TE00. The relay monitors its own Un supply voltage: The relay controls: the direct sequence of the three phases, the loss of at least one of the three phases (U measured ; 0.7 x Un), asymmetry adjustable from 5 → 15 % of Un, over- and under-voltage drift in window mode adjustable from 2 → 20 % of Un.
