For AC-4 duty (plugging, inching), it carries 29 A at 400 V — the rating that governs frequent jogging or reversing applications where contact wear accumulates faster than AC-3 cycling. ## Termination & Wiring Accepts 2x (0.75…25 mm²) stranded or 2x (0.25…2.5 mm²) solid conductors. The 16 mm² minimum at 40 °C derating ensures the power path doesn't become the thermal bottleneck in a warm cabinet. ## Switching Performance & Mechanical Life Mechanical life typical 10,000,000 operations. Maximum switching rates: 1,200 cycles/h at AC-1 (resistive), 1,000 at AC-3, 750 at AC-2, 250 at AC-4. Arcing time 10…15 ms; pick-up at AC 7…20 ms. Coil operates across 0.8…1.1 x rated voltage at 50 Hz. Side-by-side mounting allowed without derating — useful for multi-contactor motor starter groups.","metaTitle":"Siemens 3RT1034-3AF04-ZW96 SIRIUS Power Contactor, S2, 15kW","metaDescription":"Siemens SIRIUS 3RT1034-3AF04-ZW96 power contactor, size S2, rated 15 kW at 400 V AC-2, 29 A AC-4.
