Siemens 3RT2024-1AD00 SIRIUS 3RT2 Power Contactor, Size S0, 12A, 5.5kW, 42V AC, Screw Terminal Original Brand New

Product Overview

The Siemens 3RT2024-1AD00 is a highly efficient, 3-pole power contactor from the SIRIUS 3RT2 series, designed for optimal motor switching in industrial automation applications. As part of the globally proven SIRIUS modular system, this device guarantees high reliability and compact design, making it an excellent choice for motor control and switching circuits up to 5.5 kW.

This specific model features a rated operational current of 12 A (for AC-3 duty at 400 V), a 42 V AC, 50 Hz control supply voltage, and is built in the standard Size S0 frame. It is equipped with reliable screw terminals for secure wiring and includes integrated auxiliary contacts (1 NO + 1 NC) for control circuit feedback.

Benefits & Features

• Compact & Powerful: Size S0 design offers a small footprint while delivering $5.5\text{ kW}$ of power switching capacity, optimizing panel space.
• IE3/IE4 Ready: Fully compatible with high-efficiency IE3/IE4 motors, supporting modern energy standards.
• High Reliability: The SIRIUS 3RT2 series provides proven contact reliability and a long mechanical/electrical service life, minimizing downtime.
• Easy Integration: Seamlessly integrates with other components of the SIRIUS modular system (e.g., 3RU2 thermal overload relays) to build complete, tested load feeders.
• Secure Wiring: Features robust screw terminals for main and auxiliary circuits, ensuring a strong, vibration-resistant connection.
• Integrated Auxiliary Switches: Comes standard with $1\text{ NO}+1\text{ NC}$ auxiliary contacts, simplifying control circuit design and reducing wiring complexity.

Application

The Siemens 3RT2024-1AD00 Contactor is ideal for switching:

1. 3-Phase AC Motors: Start, stop, and reverse standard industrial motors up to $5.5\text{ kW}$ at $400\text{ V}$.
2. Industrial Machinery: Used in control panels for pumps, fans, compressors, and conveyors.
3. Resistance Loads: Suitable for AC-1 switching of heating elements and lighting circuits.
4. Control Systems: Essential component in motor starter combinations (direct-on-line, reversing starters).
