The AC-1 maximum switching rate of 1 200 cycles per hour means it can handle frequent resistive load switching without overheating — useful for oven or heater banks. The auxiliary contact block on this unit is rated for 10 A at 24 V AC, 6 A at 230 V, and 3 A at 400 V — these are the signal-side ratings that govern interfacing with a PLC input or a relay coil. Width is 55 mm, height 112 mm, depth 115 mm — check gland-plate clearance if the panel is shallow. Main circuit terminals are screw-type, accepting 2x (0.75... 25 mm²) stranded or 2x (0.25... 2.5 mm²) solid. The auxiliary circuit accepts 2x (0.75... 16 mm²) stranded or solid. Pollution degree 3 means it tolerates conductive pollution (dry non-conductive dust that becomes conductive with condensation) — typical for industrial control panels not in clean-room environments. Mechanical endurance is 10 000 000 operations typical, so it outlasts most panel designs.","metaTitle":"Siemens 3RT1034-3AR60 SIRIUS Power Contactor, S2, 400 V AC,","metaDescription":"Siemens SIRIUS 3RT1034-3AR60 power contactor, size S2, 400 V AC rated, 18.5 kW at 500 V, screw terminals, snap-on DIN rail mount, IP20 front.
