That's the rating that decides the fit for most three-phase motor circuits — the AC-3 figure governs switching of squirrel-cage motors under starting and running conditions. The coil pulls 6 A at 24 V rated value, drops to 1 A at 110 V and 0.3 A at 220 V. Main and auxiliary circuits both use screw-type terminals — standard for panel wiring, no special tooling needed. That helps when the panel layout is tight or the gland plate forces an odd angle. ## What the switching rates tell you Maximum mechanical switching rate is 5 000 cycles per hour for general AC use. Duty-specific limits: AC-1 (resistive loads) maxes at 1 000 1/h, AC-3 (motor starting) at 750 1/h, AC-4 (plugging/reversing) at 250 1/h. The AC-3e rating matches the AC-3 figure — 750 1/h. If your application cycles a conveyor motor every few seconds, the AC-3 limit is the one that governs contactor life. The storage range is wider because the contactor isn't switching under those extremes — just sitting on the shelf. RoHS compliance date is May 1, 2012, so it meets the EU substance restrictions that matter for equipment shipped into regulated markets.","metaTitle":"Siemens 3RT6027-1AB00 SIRIUS Power Contactor, 690 V AC-3, 45","metaDescription":"Siemens 3RT6027-1AB00 SIRIUS S0 power contactor. 690 V AC-3 rated, 45 mm wide, screw terminals.
