Schneider Electric General Purpose Relays RM4TA31

The RM4TA31 is a three-phase network control relay designed for phase failure detection, phase sequence monitoring, and asymmetry sensing in 160...300 V systems. It features two changeover contacts, a rated supply voltage of 220...240 V at 50/60 Hz, and an adjustable time delay of 0.1...10 s. The relay has screw terminals supporting flexible cables up to 2.5 mm² without end or 1.5 mm² with end, tightened to 0.6...1.1 N·m. It measures 78 mm in height, 22.5 mm in width, and 80 mm in depth, with an IP50 enclosure rating. The contacts are rated for 3 A at 250 V AC-15 and 2 A at 24 V DC-13 at 70 °C. It complies with CE directives for EMC and LVD, IEC 60664-1 overvoltage category III, and has UL, CSA, and GL certifications. Operation is permitted from -20 to 65 °C with 15...85 % relative humidity.
