Inrush current peaks at 3 A. The auxiliary contact block (attachable up to 2 units) carries rated currents that vary by voltage: 10 A at 24 V AC, 10 A at 230 V AC, and 3 A at 400 V AC. For DC switching, it handles 2 A at 48 V, 6 A at 60 V, and 1 A at 110 V. These ratings define the maximum continuous current the auxiliary contacts can break — useful for signaling to a PLC or holding in a control relay. The contactor accepts solid or stranded conductors: 2x 0.5-1.5 mm² and 2x 0.75-2.5 mm² per terminal. The screw-type terminals are straightforward for panel wiring — no special tooling needed beyond a standard screwdriver. That 6 mm side gap is tight — ensure adjacent devices or wiring ducts don't crowd the arc-chamber vents.","metaTitle":"Siemens 3RT2336-1NB30 SIRIUS Contactor, Size S2, 20-33 V AC/","metaDescription":"Siemens 3RT2336-1NB30 SIRIUS contactor, size S2, 20-33 V AC/DC coil, screw terminals.
