Product description

The Siemens 3RT1033-3AK60 is a 3-pole power contactor designed for AC-3 duty, rated for 25A and 11 kW at 400V. It features a 110V AC coil (50 Hz / 120V 60 Hz) and utilizes spring-type terminals for faster and easier wiring. This is a Size S2 contactor. This product is phased out, with the SIRIUS 3RT2 series, specifically 3RT2026-2AK60, being its successor.

Common uses include motor control for machinery, conveyor systems, and other industrial automation equipment requiring reliable AC switching.
