It carries a 6 A rated operational current at 230 V in AC-3 duty — the load category for squirrel-cage motor switching — and 3 A at 400 V. The AC-3 maximum switching rate is 800 operations per hour; the heavier AC-4 duty (inching, plugging) is limited to 250 operations per hour. ## DIN-rail mounting and panel fit The screw-type terminals on main and auxiliary circuits accept 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²) finely stranded with ferrule. ## Coil, auxiliaries, and coordination Closing power is 0.82 W DC; holding power drops to 0.24 W DC. For type of coordination 2 (limited overcurrent damage), the recommended fuse is gL/gG NH 3NA: 50 A; for type of coordination 1 (no damage), the same fuse type at 125 A. Surge voltage resistance is 6 kV, and shock resistance is 12.5g for 5 ms or 7.8g for 10 ms sine pulse.","metaTitle":"Siemens 3RT7027-1AQ00 S0 Contactor, 3-Pole, AC Coil, 45 mm W","metaDescription":"Siemens 3RT7027-1AQ00 S0 contactor, 3-pole, AC coil, 45 mm wide, 91 mm deep.
