The main contacts accept solid wire from 2.5 to 16 mm² and stranded from 6 to 70 mm², with the auxiliary contact block taking 2x (0.5 to 2.5 mm²) solid or stranded. That wire range covers most panel wiring up to a 70 mm² motor feed. The 70 mm width and 152 mm depth are the envelope to plan for on the rail. ## Duty cycle and switching frequency Switching frequency depends on the duty category. At AC-1 (resistive) it manages 900 operations per hour maximum. At AC-3 (standard motor starting) it's rated for 850 ops/h, and the AC-3e variant (enhanced motor starting with electronic overload) matches that at 850 ops/h. For heavy-duty AC-4 (plugging, inching) it drops to 250 ops/h. The arcing time sits between 10 and 20 ms, with the magnet coil operating time at 10 to 21 ms. ## Thermal environment and auxiliary contact ratings The auxiliary switch carries current ratings across voltages: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, and 0.8 A at 440 V (–). At 230 V it's rated for 20 hp. Power factor correction capacitors: 0.36 at 50 Hz, 0.4 at 60 Hz.","metaTitle":"Siemens 3RT2046-3AK60 SIRIUS Power Contactor, Size S3, Sprin","metaDescription":"Siemens 3RT2046-3AK60 SIRIUS Size S3 power contactor with spring-type terminals, 70 mm wide, screw and snap-on 35 mm DIN rail mounting, 152 mm depth.
