The AC-3 rating at 230 V is 10 A, good for a 3 kW motor at 400 V (10.5 kW) or up to 18 kW at 690 V. The coil pulls 6 A at 24 V rated value, 1 A at 110 V, 0.3 A at 220 V — check your control transformer sizing against those draws. ## DIN rail fit and wiring constraints Width of 45 mm means it occupies three 15 mm DIN-rail module positions — plan your gland plate fill factor accordingly. Screw terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded. ## Mechanical endurance and switching frequency Rated for 30 million mechanical operations typical. The maximum switching frequency varies by duty: 10 000 cycles per hour at AC general, 1 000/h at AC-1, 750/h at AC-3, 250/h at AC-4. If your application cycles a motor on and off at high rates — say a rapid-indexing conveyor — stay under the AC-3 maximum of 750/h to avoid premature contact wear. The spectrum doesn't lie: a contactor that chatters near its mechanical limit will show a 2x harmonic in the current signature before it welds. RoHS compliance date is 05/01/2012 — the part is RoHS and REACH compliant. Insulation voltage rated at 690 V, matching the AC-3 maximum operating voltage.","metaTitle":"Siemens 3RT6015-1AN21 SIRIUS Contactor, S00, 230V AC 10A AC-","metaDescription":"Siemens 3RT6015-1AN21 SIRIUS power contactor, size S00, 45 mm wide, 73 mm deep.
