The 3RT2046-1AK64-3MA0: Its footprint is 195 mm deep, 70 mm wide, and 140 mm high, so it occupies one S3 slot on a DIN rail. Wire termination: main contacts accept solid 2.5–16 mm² or stranded 6–70 mm². Coil connections are screw-type terminals; auxiliary switch is included on the contactor. Switching rates: 850 cycles/hour in AC-3 motor duty, 900 1/h in AC-1 resistive, and 250 1/h in AC-4.
No, the 3RT2046 is an S3 frame contactor, while the 3RT2028-1BB40 is a different frame size. Panel wiring and mounting differ.
195 mm deep, 70 mm wide, 140 mm tall.
Solid conductors 2.5...16 mm² and stranded conductors 6...70 mm².
