Its AC-3 duty rating of 30 kW at 400 V means it handles motor switching for loads up to that power — think conveyors, pumps, or compressors in a standard 400 V three-phase line. The 120 VAC coil (110 V 50 Hz / 120 V 60 Hz) pulls in reliably across that range; verify your control transformer taps if you're running at 50 Hz. Screw terminals accept up to the rated conductor size; the modified shunt ring is a factory-fit option that reduces arc-blow on high-inrush loads, so if you're switching a transformer or a capacitor bank, that ring is already in place. Coil draw at 120 VAC is modest — no separate control transformer derating for a single contactor, but watch the cumulative VA if you're ganging several on one transformer.","metaTitle":"Siemens 3RT10441AK600ST0 Contactor, 65A 120VAC 3P, AC-3 30kW","metaDescription":"Siemens 3RT10441AK600ST0 contactor, 65A at 120VAC, AC-3 rated 30kW at 400V.
