Product details

Siemens 3RT2047-3AF00 — SIRIUS Size S3 Power Contactor

Its headline rating is 96 A at 480 V — that is the continuous current it can carry in AC-3 duty, so it handles a 50 hp motor at 480 V three-phase without derating.

The 96 A at 480 V rating governs the main power path — this is the AC-3 current for starting and running squirrel-cage motors. For resistive loads (AC-1), the contactor can cycle at up to 900 operations per hour, while motor starting (AC-3) allows 850 ops/h, and plugging/reversing (AC-4) drops to 200 ops/h. Wire sizing is generous: solid conductors from 2.5 to 16 mm² and stranded from 6 to 70 mm² fit the main terminals.

The contactor measures 70 mm wide, 140 mm tall, and 152 mm deep.
