Siemens 3RT1064-2AS36 Power Contactor SIRIUS 3RT1 225A, 110kW, 500-550V UC, Spring Terminal Original Brand New

Overview

The Siemens 3RT1064-2AS36 Power Contactor from the renowned SIRIUS 3RT1 series is a robust, high-performance industrial switching device designed for critical applications such as motor control and high-current load switching. Engineered by Siemens, this 3-pole contactor is rated for $225\text{ A}$ at $400\text{ V}$ with a power capacity of $110\text{ kW}$ (AC-3e/AC-3 rating).

It features a wide-range control voltage of $500\text{-}550\text{ V}$ for both $\text{AC }(50\text{-}60\text{ Hz})$ and $\text{DC}$ operation, ensuring versatility in various electrical systems. The main circuit employs a reliable busbar connection for high current carrying capacity, while the control and auxiliary circuits utilize user-friendly spring-loaded terminals (often referred to as Cage Clamp) for fast, vibration-proof wiring.

Function

The 3RT1064-2AS36 serves to safely switch on and off electric motors or other high-power loads. The $500\text{-}550\text{ V UC}$ coil activates the conventional drive mechanism, closing the three main contacts to supply power to the load. The integrated $2\text{ NO}+2\text{ NC}$ auxiliary contacts provide essential feedback for control and interlocking circuits.

Key Benefit

• High Performance: Handles large loads with a substantial $225\text{ A}$ current and $110\text{ kW}$ power rating, ideal for heavy-duty industrial machinery.
• Flexible Control: Universal $500\text{-}550\text{ V AC/DC}$ (UC) coil voltage minimizes inventory and simplifies selection.
• Reliable Connections: Busbar connection on the main circuit ensures maximum current transmission and simplified power distribution in panels.
• Fast, Secure Wiring: Spring-loaded terminals (Cage Clamp) on the control and auxiliary circuits provide quick, maintenance-free, and vibration-resistant connections.
• Integrated Monitoring: Built-in $2\text{ NO}+2\text{ NC}$ auxiliary contacts provide standard signaling for motor status and control logic.

Application

The Siemens 3RT1064-2AS36 Power Contactor is typically used in:

• Motor Starters (DOL, Reversing) for high-power motors
• Heating, Ventilation, and Air Conditioning (HVAC) systems
• Pumping stations and water treatment facilities
• Heavy machinery and conveyor systems
• Industrial control panels requiring high-current switching
