Product details

Siemens 3RT6028-1AM00 is a SIRIUS power contactor in size S0, screw-type terminals, rated for AC-3e switching at 21 A up to 690 V. Motor power ratings at 60 °C ambient: 15.5 kW at 230 V, 27.5 kW at 400 V, 47.5 kW at 690 V — the 690 V figure matters for 690 VAC distribution in data-center or industrial plants where a single contactor must handle the line voltage without an intermediate transformer.

Width 45 mm, depth 97 mm, height 85 mm — fits a standard 45 mm DIN slot. Side-by-side mounting allowed, so no derating for tight packing in a multi-contactor panel.
