Rated operational current at 24 V is 10 A, dropping to 6 A at 230 V and 3 A at 400 V — these are the AC-1 resistive load ratings that define its continuous current-carrying capacity in open air. The AC-3 motor switching rating at 400 V is 3.5 kW (4 kW at 690 V), which tells you the maximum three-phase induction motor this contactor can switch under full load without accelerated contact wear. For a 3.5 kW motor on a 400 V line, that's roughly 7.5 A full-load current — the contacts are sized for that duty cycle. Mechanical endurance of 30 million operations means the actuator and spring mechanism are rated for that many cycles before mechanical failure. Electrical endurance will be lower depending on the switched current — at full AC-3 rating, expect around 1–2 million operations before contact replacement is due. This is standard for panel-mounted contactors — it's not for washdown environments without an additional enclosure. Screw-type terminals for both main and auxiliary circuits accept solid or stranded conductors: 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), max 2x (0.75–4 mm²). AWG equivalents: 2x (20–16), 2x (18–14), 1x 12. The dual-wire entry is useful for daisy-chaining control wiring without additional terminal blocks. For a BOM freeze or line-down replacement, the 3RT1015-1AB01 is a direct fit for any panel designed around the Size S00 SIRIUS contactor footprint. The 24 VAC coil variant is common in European-origin panels with 24 V control transformers.","metaTitle":"Siemens SIRIUS 3RT1015-1AB01 Power Contactor, 24 VAC 50/60 H","metaDescription":"Siemens SIRIUS 3RT1015-1AB01 power contactor, 24 VAC 50/60 Hz coil, Size S00 frame, IP20.
