Siemens 3RT2027-1FB44-3MA0 SIRIUS 3RT2 Power Contactor, 3-Pole, 32A, 15kW, 24V DC Coil, Size S0, Screw Terminals Original Brand New

Overview: High-Performance 3-Pole Power Contactor

The Siemens 3RT2027-1FB44-3MA0 is a highly efficient, 3-pole SIRIUS 3RT2 power contactor designed for reliable switching of motors and other industrial loads. As a member of the modular SIRIUS system, it offers a compact design and high contact reliability, making it the ideal choice for modern industrial control applications. This specific model is engineered for robust performance and high availability.

Benefit & Advantages

1. High Reliability & Service Life: Built for demanding industrial environments, featuring a mechanical service life of up to 10,000,000 switching cycles (typical).
2. Space-Saving Design (Size S0): The compact dimensions of the SIRIUS 3RT2 series save valuable space in control cabinets compared to predecessor models.
3. Enhanced Surge Protection: The plugged-in diode combination effectively dampens coil surges, protecting sensitive control system components like PLC outputs.
4. Integrated Auxiliary Contacts: Features a captive auxiliary switch block with $2\text{ NO}+2\text{ NC}$ contacts, reducing complexity and wiring effort for monitoring and interlocking functions.
5. Globally Approved: The 3RT2 series is approved for worldwide use (e.g., IEC and UL/CSA) and is IE3/IE4-ready, ensuring suitability for energy-efficient motor applications.
6. Secure Connections: Reliable screw terminals provide a secure, high-contact force connection for main and auxiliary conductors.

Function & Typical Applications

The Siemens 3RT2027-1FB44-3MA0 serves as the core switching element in motor control circuits.

• Motor Switching: Primarily used for switching 3-phase motors up to $15\text{ kW}$ at $400\text{ V}$ (AC-3 rating).
• Safety Applications: The captive auxiliary switch configuration makes this model suitable for safety-related applications requiring permanently mounted auxiliary contacts (often required for certain safety regulations like SUVA).
• Load Switching: Suitable for general resistive and inductive load switching, including heating, lighting, and ventilation systems (AC-1 rating up to $50\text{ A}$).
• Integration: Seamless integration into the SIRIUS modular system allows for simple connection with overload relays (like 3RV2) and other function modules.
