Overview: High-Performance SIRIUS 3RT2 Power Contactor
The Siemens 3RT2028-2FB44-3MA0 is a high-performance SIRIUS 3RT2 Power Contactor designed for switching motors and other resistive loads in industrial control applications. As a key component in the SIRIUS modular system, this size S0 contactor combines a compact design with robust capabilities, ensuring reliable and energy-efficient operation.
It is rated for AC-3e/AC-3 operation up to 38 Amps and 18.5 kW at 400V. The coil operates on a 24 V DC voltage, and for enhanced protection and operational life, it includes a plugged-in diode combination to suppress coil opening voltage peaks. Its main features include a secure spring-loaded terminal connection for quick, vibration-proof wiring and integrated auxiliary switches (2 NO + 2 NC) for monitoring and control circuits.
Benefit
- Reliable DC Operation: The 24V DC coil with an integrated plugged-in diode combination provides reliable, low-consumption control and excellent surge suppression, protecting your sensitive control electronics.
- Secure & Fast Wiring: The spring-loaded terminals ensure permanent, vibration-proof contact, significantly reducing wiring time and increasing the reliability of your system. Ideal for industrial environments where vibration is a concern.
- Compact Design: As a size S0 contactor, the 3RT2028-2FB44-3MA0 saves valuable space within your control cabinet without compromising on performance.
- Enhanced Control Flexibility: The pre-installed 2 NO + 2 NC captive auxiliary switch contacts offer immediate feedback and control functionality for interlocking, signaling, and sequence control.
- Industry Standard: Part of the trusted Siemens SIRIUS family, guaranteeing high quality, long service life (mechanical service life is typically 10,000,000 operating cycles), and compatibility with other SIRIUS components.
Function
The Siemens 3RT2028-2FB44-3MA0 primarily functions as an electromechanical switching device for safely and reliably switching three-phase loads, most commonly AC motors. It is suitable for applications requiring high switching frequency, remote control of machinery, and integration into automated systems (PLC-controlled systems utilizing a 24 V DC output).
