Siemens 3RT1066-6AF36-3PA0 Power Contactor 3-Pole, 300A, AC-3 / 160 kW, 400V Original Brand New

Overview

The Siemens 3RT1066-6AF36-3PA0 is a robust, high-performance power contactor from the globally recognized SIRIUS 3RT1 series, designed for reliable switching of motors and other high-current loads up to 300 A (AC-3e/AC-3).

This 3-pole contactor is engineered for demanding industrial environments, rated for a motor power of 160 kW at 400 V. It features a conventional drive for the solenoid coil, operating on a versatile 110-127 V AC (50/60 Hz) / DC control supply voltage, making it suitable for both AC and DC control systems.

The main circuit connection is via busbar, ideal for efficient power distribution in control panels and motor control centers (MCCs). The control and auxiliary circuits utilize reliable screw terminals for secure wiring. This unit comes complete with 2 NO + 2 NC permanently mounted auxiliary contacts for signaling and interlocking purposes, simplifying installation.
