Siemens SIRIUS 3RT1064-6AB36-3PA0 Power Contactor, 225A, 110kW, AC/DC 23-26V Coil, Size S10 Original Brand New

Overview

The Siemens SIRIUS 3RT1064-6AB36-3PA0 is a high-performance, 3-pole power contactor from the robust SIRIUS 3RT series, designed for switching electric motors up to 250 kW. This particular model is rated for an operational current of 225 A (AC-3e/AC-3) at $400\text{ V}$, corresponding to a power rating of 110 kW.

It features a versatile, conventional operating mechanism with a low-voltage control coil that accepts a wide range of control supply voltages: 23-26 V AC (50-60 Hz) or DC (Uc: 23-26 V). The contactor is engineered for use in demanding industrial environments, offering high contact reliability and a long mechanical service life.

Key Benefits and Features

High Power & Reliability

• Function: Capable of switching motor loads up to $110\text{ kW}$ ($400\text{ V}$) and handling an operational current of $225\text{ A}$, making it ideal for large industrial motors and demanding applications.
• Feature: High contact reliability and long service life (typically 10 million mechanical operating cycles).

Flexible Control Voltage

• Function: The conventional drive mechanism with an extended voltage range coil allows control via a single low-voltage supply, compatible with both AC and DC sources ($23\text{–}26\text{ V}$ Uc). This simplifies inventory and control panel design.
• Feature: AC (50-60 Hz) / DC operation coil (Uc: 23-26 V).

Integrated Auxiliary Contacts

• Function: The permanently mounted auxiliary contacts provide immediate feedback and control signals to the automation system (PLC/DCS) without the need for additional, snap-on blocks.
• Feature: 2 NO + 2 NC auxiliary contacts, built-in standard.

Robust Connection System

• Function: Ensures secure and high-current connections for the main power circuit, while the control connections use reliable screw terminals for easy wiring of the control logic.
• Feature: Main circuit connection via Busbar for high-current transfer; control/auxiliary circuit via Screw Terminals.
