Siemens 3RT1064-6XB46-0LA2 Power Contactor 225A, 110kW, 24V DC, PLC Compatible Original Brand New

Overview

The Siemens 3RT1064-6XB46-0LA2 is a high-performance power contactor designed for demanding industrial applications. With a robust rating of 225 A for AC-3e/AC-3 operation and a power rating of 110 kW at 400 V, this 3-pole contactor is engineered for reliable switching of motors and other high-current loads. Its versatile design features an electronic drive with a 24 V DC control voltage range (Uc​:24 V DC ×(0.7−1.25)), and is equipped with a PLC input for 24-110 V DC, making it highly compatible with modern automation systems.

The inclusion of two normally open (2 NO) and two normally closed (2 NC) auxiliary contacts provides flexibility for control and signaling circuits. This model is specifically designed to meet the extended rated conditions for railroad applications according to IEC 60077, ensuring exceptional durability and performance in harsh environments. The main circuit connection is via busbars, while the control and auxiliary circuits use convenient screw terminals for easy installation.
