The coil is rated for 50/60 Hz operation at 220 V; the operating range spans 0.8 to 1.1 times rated voltage at 50 Hz and 0.85 to 1.1 at 60 Hz, so it holds in on a sagging line but drops out cleanly below the undervoltage threshold. Mechanical life is listed at 10,000,000 operations typical, and the contactor supports operating frequencies up to 1,000 cycles per hour under AC-3 duty — enough for frequent start-stop conveyor or pump applications. ## Mounting and integration in the panel The S2 frame is 55 mm wide, 112 mm high, and 115 mm deep — a standard footprint that fits alongside other SIRIUS S2 components without extra spacing. Side-by-side mounting is permitted, which saves rail space in dense panels. Auxiliary contact terminals accept solid 0.5 to 1.5 mm² or stranded 0.75 to 2.5 mm². ## Auxiliary contact ratings and switching times The auxiliary contacts are rated for 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — all AC values. At 110 V the rating drops to 1 A, and at 220 V to 0.3 A. These are the switching capacities, not continuous carry; use them for PLC inputs or indicator lamps within those limits.","metaTitle":"Siemens 3RT1033-1AN20 SIRIUS Power Contactor, S2, 15 kW at 4","metaDescription":"Siemens 3RT1033-1AN20 SIRIUS S2 power contactor.
