Siemens SIRIUS 3RT2024-2AL24-3MA0 Power Contactor, 12A, 5.5kW, 230V AC Coil, 3-Pole, Spring-Loaded Terminal, Size S0 Original Brand New

Overview

The Siemens 3RT2024-2AL24-3MA0 is a high-performance, 3-pole power contactor from the globally recognized SIRIUS 3RT2 modular system. Engineered for switching motors and general industrial applications, this device ensures reliable and durable operation. It is rated for AC-3e/AC-3 duty with a nominal operational current of 12 A and a power rating of 5.5 kW at 400 V. The compact Size S0 design and robust construction make it a cornerstone for efficient load feeders in modern automation and control systems.

Benefit

1. Fast and Reliable Wiring: Utilizes spring-loaded terminals for vibration-proof, maintenance-free, and time-saving connection compared to traditional screw terminals.
2. Safety Compliant: Features a captive auxiliary switch (2 NO + 2 NC), often required for specific safety-related applications (e.g., SUVA), ensuring a secure circuit setup.
3. Space Efficiency: The compact Size S0 design of the SIRIUS 3RT2 series allows for optimal panel layout and space saving in control cabinets.
4. High Compatibility: Part of the modular SIRIUS system, enabling easy combination with overload relays, circuit breakers, and accessories for comprehensive motor starting solutions.
5. Global Standard: IE3/IE4-ready and approved for worldwide use (e.g., IEC and UL/CSA), guaranteeing suitability for international projects.

Application

This Siemens power contactor is primarily used for the reliable and efficient switching of:

• Standard AC Motors (up to 5.5 kW at 400V)
• Heating systems
• Lighting circuits
• Ventilation systems
• Other resistive and slightly inductive loads in industrial automation, machinery, and plant construction.
