Siemens 3RT2038-1AK60 Three-Phase Power Contactor

Siemens 3RT2038-1AK60 is a three-pole power contactor from the SIRIUS line, engineered for AC-3e/AC-3 motor control. It delivers an 80 A nominal current rating and switches up to 37 kW at 400 V for reliable start/stop of three-phase motors in industrial equipment. The control coil accepts 110 V AC at 50 Hz or 120 V AC at 60 Hz, ensuring compatibility with common control power supplies, and the contactor includes one normally open and one normally closed auxiliary contact for simple interlocking or feedback signals. This size-S2, tripolar device uses screw terminals for robust wiring and is designed to work with Siemens accessories as part of integrated control cabinets in industrial settings. Typical applications span conveyors, pumping stations, HVAC fans, compressors, and other machinery where compact, durable motor switching with integrated signaling is required.
