Rated at 15 kW at AC-2 duty at 400 V, this contactor handles slip-ring motor loads or other moderate-inductive switching. At AC-4 at 400 V it carries 29 A, covering reversing or inching applications with high electrical stress on the contacts. The terminal block accepts solid conductors 2x (0.25 to 2.5 mm²) and stranded conductors 2x (0.75 to 25 mm²), with a minimum permissible cross-section of 16 mm² at 40 °C. Side-by-side mounting is permitted, which simplifies dense panel layouts. ## Duty Ratings and Switching Life Switching frequency limits are specified per duty class: 1200 cycles/hour at AC-1 (resistive), 750 at AC-2, 1000 at AC-3 (standard squirrel-cage motor start), and 250 at AC-4. At 500 V the contactor is rated for 18.5 kW; at 690 V it drops to 10 kW — the voltage derating reflects the increased arc energy at higher potentials. The enclosure is rated IP20 on the front (finger-safe) and IP00 at the terminals (no protection at the connection points — panel builders must account for this in the enclosure design). Built-in auxiliary contacts (likely 1 NO + 1 NC, per SIRIUS convention for this frame) are rated: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. These cover typical control circuit voltages across global standards. Dimensions: 112 mm height, 55 mm width, 115 mm depth. S2 frame, 55 mm width.","metaTitle":"Siemens 3RT1034-3AF00-ZX95 SIRIUS Power Contactor, S2 Frame,","metaDescription":"Siemens SIRIUS 3RT1034-3AF00-ZX95 power contactor, S2 frame size.
