Maximum operating rate varies by duty: 1,200 cycles/hour under AC-1 (resistive), 1,000 under AC-3 (cage motor), and 250 under AC-4. ## Termination and wiring Main circuit terminals are screw-type, accepting solid conductors from 2x (0.5... 1.5 mm²) up to max 2x (0.75... 4 mm²) and stranded from 2x (0.75... 25 mm²). Minimum cross-section at 40 °C is 16 mm² — relevant if the panel runs warm and you are sizing the main power wiring to avoid terminal overheating. Front-of-device protection is IP20 (finger-safe terminals); the terminal area itself is IP00 — so the panel enclosure must provide the environmental seal. The lifecycle stage is listed as current — meaning the manufacturer continues to produce and support this order code as an active catalog item.","metaTitle":"Siemens 3RT1034-1AF00-1AA0 SIRIUS S2 Power Contactor, 15 kW","metaDescription":"Siemens 3RT1034-1AF00-1AA0 SIRIUS S2 power contactor, 15 kW at 400 V AC-2, 29 A AC-4.
