Siemens 3RT2028-1AP60 Three-Phase Contactor 38 Amp

Siemens 3RT2028-1AP60 is a three‑pole power contactor (size S0) in the Sirius 3RT2 motor starter line, engineered for AC-3e/AC-3 control of industrial motors. It handles up to 38 A and enables motor switching of up to 18.5 kW at a 400 V three‑phase supply, making it suitable for pumps, fans, conveyors, and other common industrial loads. The coil is rated for 220 V AC at 50 Hz (and 240 V AC at 60 Hz), allowing reliable energization from standard control circuits, while the auxiliary section provides 1 normally open and 1 normally closed contact for signaling, interlocking, or control logic. Main and auxiliary connections use screw terminals for secure wiring, and the device is designed to integrate with Siemens 3RT control systems in compact envelope applications. The part number 3RT2028-1AP60 explicitly denotes a 3‑pole unit with one NO and one NC auxiliary contact, enabling straightforward integration into motor control schemes and panel layouts where reliable, code‑compliant switching of 3‑phase motors is required.
