The 55 mm width and 112 mm height fit standard panel layouts; the 115 mm depth accounts for the terminal clearance and arc chamber. The contactor carries a mechanical life of 10 million operations typical, with maximum switching frequencies of 1,200 cycles/hour at AC-1, 1,000 at AC-3, and 250 at AC-4. The operating temperature range is -25 to +60 °C, storage from -55 to +80 °C, and the pollution degree is rated 3 (conductive pollution or dry non-conductive that becomes conductive). ## Terminal and Wiring Capacity The main circuit screw terminals accept solid conductors 2x (0.25 to 2.5 mm²) and stranded 2x (0.75 to 25 mm²), with a separate entry for 2x (0.75 to 16 mm²) solid or stranded. This range covers most control and power wiring from signal-level to 25 mm² feeder cables. The integrated auxiliary contacts are rated for 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 2 A at 60 V, with lower ratings at 110 V (1 A) and 220 V (0.3 A). These cover PLC-level signal switching and control relay loads within the contactor's own coil circuit.","metaTitle":"Siemens 3RT1034-3AK60 SIRIUS Power Contactor, 18.5 kW at 500","metaDescription":"Siemens 3RT1034-3AK60 SIRIUS power contactor, size S2, screw terminals, 18.5 kW at 500 V AC-3.
