More info
Purpose - it is possible to control the phase sequence and absence in a three-phase network, intended for the protection of electric motors from phase loss or sequence change. It is possible to control the voltage Umax and Umin limits, adjust the delay in case of voltage jumps. Umax 105-125% Un, U min 75-95% Un. Delay t1 max. 500ms. Delay t2 0.1-10 sec. Wire cross-section max. 1 x 4 mm², 2 x 2.5 mm². The relay operates even if one of the phases is missing.
