Siemens SIRIUS 3RT1056-6AV36 Power Contactor 185A, 90kW, 380-420V AC/DC Coil, Size S6 Original Brand New

Overview

The Siemens 3RT1056-6AV36 is a robust, high-performance SIRIUS 3RT1 power contactor designed for switching motors and electrical loads up to 185 A (AC-3) and 90 kW at $400\text{V}$. Part of the modular SIRIUS industrial controls system, this 3-pole contactor (Size S6) is built for exceptional reliability and high contact dependability in demanding industrial applications.

It features a wide-voltage conventional drive capable of operating with a control supply voltage Uc​ of $380-420\text{V AC}/\text{DC}$ for maximum flexibility. The main circuit utilizes reliable busbar connection, while the control and auxiliary circuits are equipped with traditional screw terminals for secure wiring.

Benefit

• IE3/IE4 Ready: Optimized for switching the latest generation of highly-efficient IE3/IE4 motors, meeting modern energy standards.
• High Power Density: Delivers up to 90 kW switching capacity in a compact, space-saving Size S6 design.
• Universal Control: Wide-range AC/DC operation ($\text{Uc}:380-420\text{V}$) reduces inventory and simplifies selection.
• Reliable Integration: Features pre-installed $2\text{NO}+2\text{NC}$ auxiliary contacts, making integration into complex control systems straightforward.
• Robust & Durable: Engineered for long mechanical and electrical service life in harsh industrial environments.

Function

The Siemens 3RT1056-6AV36 functions as a primary switching device for three-phase asynchronous motors and general electrical loads. It reliably establishes and interrupts the flow of power to the load (AC-3/AC-3e operation) based on the control signal applied to its coil. The integrated $2\text{NO}/2\text{NC}$ auxiliary contacts provide status feedback and interlocks for external control circuits, motor starters, and automation systems (PLCs).
