Siemens 3RT2023-2AV00 SIRIUS 3RT2 Power Contactor, 9A, 4kW, 400V AC Coil, Size S0, Spring Terminal Original Brand New

Overview

The Siemens 3RT2023-2AV00 SIRIUS 3RT2 Power Contactor is a high-performance, compact 3-pole switching device engineered for efficient motor control in industrial applications. As part of the highly successful SIRIUS modular system, this contactor offers exceptional reliability, a long mechanical lifespan (up to 10 million operating cycles), and a narrow, space-saving design, making it a cornerstone for modern motor feeders and control panels.

Benefit

• Quick & Secure Wiring: The spring-loaded (spring-cage) terminal technology ensures fast, maintenance-free, and vibration-proof connections, significantly reducing installation time and increasing operational reliability compared to traditional screw terminals.
• High Performance in a Compact Design: The Size S0 frame allows for high power switching (9A, 4kW) while maintaining a minimal footprint, enabling denser cabinet layouts.
• Enhanced Compatibility: Optimized to seamlessly integrate with other SIRIUS components, such as thermal overload relays (SIRIUS 3RU2) and motor circuit protectors (SIRIUS 3RV2), facilitating the quick assembly of complete load feeders.
• Integrated Auxiliary Contacts: The built-in 1 NO + 1 NC auxiliary contacts simplify control circuit design, providing immediate feedback for monitoring and interlocking without the need for additional side-mounted blocks.
• Global Certification and Climate Resistance: Certified for worldwide use (IEC, UL/CSA) and designed to be climate-resistant, ensuring reliable operation in harsh industrial environments from −25∘C to +60∘C.

Function and Application

The 3RT2023-2AV00 functions as an electromechanical switch designed to remotely control the flow of electrical power to a load, typically an electric motor.

1. Motor Switching: Primarily used for switching 3-phase AC motors up to 4 kW at 400V (AC-3 duty).
2. General Resistive Loads: Also suitable for switching general AC-1 loads up to 40A.
3. Control Integration: The integrated auxiliary contacts (1 NO, 1 NC) provide feedback to a PLC (Programmable Logic Controller) or other control system, indicating the contactor’s ON/OFF status.
4. Applications: Ideal for use in fans, pumps, conveyors, machining tools, and any application requiring robust, reliable, and frequent switching of a motor load.
