Siemens 3RT2046-1AK60 Three-Phase Magnetic Contactor

Siemens 3RT2046-1AK60 is a three-pole power contactor designed for AC-3 motor switching. It is rated for 95 A (AC-3) and up to 45 kW at 400 V, with three normally open main contacts and an integrated auxiliary contact set consisting of one normally open and one normally closed contact, making it suitable for motor control circuits requiring feedback or interlocking. The coil is rated 110 VAC at 50 Hz (and 120 VAC at 60 Hz), enabling straightforward integration with standard control circuitry, and the device uses screw terminals for both main and auxiliary circuits. Sized for compact installation in panel boards and motor control cabinets (size S3), the 3RT2046-1AK60 is a reliable choice for starting and stopping medium-sized three-phase motors in industrial environments such as pumps, fans, conveyors, and other automation equipment where robust AC-3 duty switching is required.
