The Siemens SIRIUS 3RT2028-4AP00 is a size S0 power contactor rated for motor switching at 34 A on 480 V and 27 A on 600 V — those are the AC-3 duty figures that govern real motor loads, not the higher AC-1 resistive rating.
Side clearance of 6 mm to adjacent devices keeps the arc chamber clear.
Submit an RFQ through the distributor; availability and current pricing are confirmed at quote time.
Both are size S0 contactors sharing the same 45 mm width and 35 mm DIN-rail mounting, so they occupy the same footprint. Verify the coil voltage and auxiliary contact configuration on the 3RT2015-4AP62 before substituting — those may differ.
Rated 34 A at 480 V and 27 A at 600 V under AC-3 duty (motor switching). The coil circuit uses a ring cable lug connection. Operating temperature range -25 to +60 °C; storage -55 to +80 °C.
