At 500 V it handles 18.5 kW; at 690 V it drops to 10 kW, so the voltage derating is steep above 500 V. Terminals accept solid conductors: 2x (0.5 … 1.5 mm²), 2x (0.75 … 2.5 mm²), max. 2x (0.75 … 4 mm²). At 40 °C the minimum permissible cross-section is 16 mm², so for full-rated current you need at least that gauge on the power path. The contactor occupies 55 mm width, 112 mm height, 164 mm depth — verify clearance for the screw-terminal wiring arc and the 10–15 ms arcing time when spacing from grounded metal. Mechanical endurance is typical 10,000,000 operations. Maximum switching frequency varies by duty: AC-1 at 1,200 cycles/h, AC-2 at 750, AC-3 at 1,000, AC-4 at 250. For high-cycle reversing or jogging applications, the AC-4 limit is the binding constraint.","metaTitle":"Siemens SIRIUS 3RT1034-1AP04-1AA0 Power Contactor, Size S2,","metaDescription":"Siemens SIRIUS 3RT1034-1AP04-1AA0 power contactor, Size S2, rated 15 kW at AC-2 400 V, 29 A AC-4.
