For heavy jogging or plugging duty (AC-4), it's rated to break 80 A at 400 V, so it survives the high-stress reversals on a crane or conveyor that cycles hard. Dimensions are 146 mm high, 90 mm wide, 139 mm deep — that depth matters when you're laying out a gland plate or a shallow enclosure; the 139 mm leaves room for wiring clearance behind the panel door. ## Termination and Wiring Main circuit terminals are screw-type, accepting solid conductors 2x (0.25...2.5 mm²) and stranded 2x (10...50 mm²). The stranded range covers the typical motor feeder cable for a 55 kW load — you'll land a 25 or 35 mm² cable on the line and load side. The smaller solid range handles the control wiring for the coil and auxiliaries. IP20 on the front with the cover installed; the terminal area itself is IP00, so keep the cover on during operation. RoHS compliance date is May 1, 2012, so it meets the EU directive for new equipment.","metaTitle":"Siemens 3RT1046-3AF06 SIRIUS Power Contactor, 55 kW at 400 V","metaDescription":"Siemens SIRIUS 3RT1046-3AF06 power contactor, S3 size, rated 55 kW at 400 V AC-3.
