RM17UB310
Schneider Electric RM17UB310 Voltage control relay, 5A, 1 C/O, 208-480V AC. Schneider Electric's RM17UB310 is a robust 3-phase voltage control relay designed to protect critical plant equipment by monitoring for both overvoltage and undervoltage conditions between phases. This self-powered device features a versatile measurement range of 220-480V AC and offers a reliable 5A nominal output current through its 1 C/O contact, capable of switching up to 250V AC/DC. Engineered for industrial environments, it operates effectively within a 50-60 Hz frequency range and features an adjustable time delay from 0.3 to 30 seconds for precise fault response. With an IP20 (terminals) and IP30 (casing) degree of protection, and certified by GOST, UL, GL, C-Tick, CSA, the RM17UB310 ensures dependable performance. It is ideal for safeguarding machinery in diverse applications across Egypt and the Gulf, including motor control in cement plants, pumping stations in water treatment facilities, critical systems in oil and gas operations, and power distribution in food and beverage or textile industries. Its compact design allows for easy 35 mm DIN rail mounting.
