The enclosure is IP20 on the front with the cover or box terminal fitted; the terminal area itself is IP00, so the panel environment must provide the final ingress protection. Dimensions are 146 mm high, 70 mm wide, and 139 mm deep. ## Terminals and wiring Solid conductors: accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²). Stranded conductors: 2x (10 to 50 mm²). The auxiliary contact block (integrated) is rated 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — these are the switching limits for the built-in aux contacts, not the main poles. RoHS compliance date is May 1, 2012, which covers the EU RoHS recast. The contactor is rated for 50 Hz systems. ## Switching performance and life Maximum switching rates: 900 cycles/hour at AC-1 (resistive), 850 at AC-3 (squirrel-cage motors), 350 at AC-2, and 250 at AC-4. Arcing time is 10 to 25 ms at AC, with a narrower 10 to 15 ms typical window. The operating voltage range factor is 0.8 to 1.1 at 50 Hz, so the coil holds in down to 80% of rated voltage. ## Power dissipation Dissipates 37 W at 1000 V — a figure to include in thermal panel calculations when the contactor is continuously energized.","metaTitle":"Siemens SIRIUS 3RT1046-1AM00-1AA0 Power Contactor, Size S3,","metaDescription":"Siemens SIRIUS 3RT1046-1AM00-1AA0 power contactor, size S3, rated 80 A at 400 V AC-4.
