SIRIUS S3 power contactor, 96 A AC-3, 24 VDC coil
The Siemens 3RT2047-3AB00 is a SIRIUS S3-size power contactor rated 96 A in AC-3 duty at 480 V, so it switches three-phase motor loads up to that current — common for 50 hp class motors on 400/480 V lines. The coil is 24 VDC, spring-type terminals, with a pickup at 24 V rated value drawing 10 A inrush — verify your DC supply can deliver the peak without dropout on the control bus.
The S3 frame measures 140 x 70 x 152 mm (H x W x D) — fits standard panel cutouts with 10 mm clearance required upwards, downwards, and sideways.
