For AC-2 duty (slip-ring motors, or where the load is mostly resistive during switching) it's rated 15 kW at 400 V. ## Mounting and wiring — what fits Auxiliary and coil wiring takes solid conductors 2x 0.25 to 2.5 mm². ## Switching frequency and auxiliary ratings Maximum mechanical switching frequency is 10 million operations typical. Electrical frequency depends on duty: 1200 cycles/hour at AC-1 (resistive), 1000 at AC-3 (motor), 250 at AC-4 (plugging/reversing). The built-in auxiliary contacts are rated 10 A at 24 V, 6 A at 230 V, and 0.3 A at 220 V DC — enough for PLC inputs or relay coils in the control circuit.","metaTitle":"Siemens 3RT1034-3AG60 SIRIUS Power Contactor, 18.5 kW at 500","metaDescription":"Siemens SIRIUS 3RT1034-3AG60 power contactor, size S2, rated 18.5 kW at 500 V AC-3.
