It switches main circuits up to 690 V and is rated for 9 A in AC-3e service, with a 4 kW / 400 V load rating. The device uses screw-terminal connections in the S00 size and weighs about 0.29 kg. The coil operates at 24 V DC, with coil power loss around 0.9 W per rated coil (0.3 W per pole) in hot state. Built for industrial environments, it supports ambient operation from -25 to +60 °C and up to 2,000 m altitude, and provides mains insulation rated to 690 V and surge resistance of 6 kV on the main circuit (6 kV on the auxiliary circuit). The unit includes one auxiliary NO contact for control circuits and is part of Siemens’ Sirius 3RT2 line, making it suitable for motor control and general load switching in control panels and automation cabinets.
