The standing position on a horizontal surface is the specified orientation. Panel integration is straightforward — the 70 mm width and 140 mm height leave room for a thermal overload relay alongside on the rail. The AC-3 switching frequency is rated at 850 operations per hour maximum. AC-4 (plugging / inching) drops to 200 ops/h. Its contact ratings cover the common control voltages: 10 A at 24 V, 1 A at 110 V, 0.3 A at 230 V, and 3 A at 400 V. Wire range is generous: solid conductors from 2.5 to 16 mm², stranded from 6 to 70 mm². Depth is 152 mm. ## Environmental range No IP rating is listed, so it is intended for enclosure mounting, not open washdown.","metaTitle":"Siemens SIRIUS 3RT2047-1AB00-1AA0 Power Contactor, 96 A AC-3","metaDescription":"Siemens SIRIUS 3RT2047-1AB00-1AA0 power contactor, 96 A AC-3 rated, S3 frame, screw terminals, auxiliary switch included.
