Overview

The Siemens SIRIUS 3RT2028-2AN24 is a high-performance, 3-pole power contactor designed for reliable switching of motors and general industrial loads (AC-3e/AC-3). Part of the trusted SIRIUS modular system, this contactor offers a compact design, high contact reliability, and rapid, vibration-proof wiring thanks to its integrated spring-loaded terminals. Ideal for applications requiring robust motor control up to 18.5 kW at 400 V and controlled by a common 220 V AC (50/60 Hz) coil voltage. The built-in auxiliary contact configuration (2 NO + 2 NC) and the removable auxiliary switch feature offer maximum flexibility and integration into complex control circuits.

Benefit

  • Fast and Reliable Wiring: The spring-loaded terminal technology ensures a secure, vibration-proof, and maintenance-free connection, significantly reducing installation time and increasing operational reliability in demanding industrial environments.
  • Space-Saving Design: As a size S0 contactor, the compact design allows for high-density panel mounting, making it a perfect fit for modern, space-constrained control cabinets.
  • Enhanced Control Flexibility: Equipped with 2 Normally Open (NO) and 2 Normally Closed (NC) auxiliary contacts and a removable auxiliary switch for easy customization of control and signalling circuits.
  • Global Compliance: The SIRIUS 3RT2 series is approved for worldwide use (e.g., IEC and UL/CSA), ensuring compatibility and acceptance for export-oriented machinery.
  • IE3/IE4 Ready: Optimized for switching high-efficiency IE3/IE4 motors, supporting energy-efficient machine designs.

Function / Application

The 3RT2028-2AN24 is primarily used in automation technology and low-voltage controls for:

  • Switching 3-Phase AC Motors (e.g., pumps, fans, compressors) up to 18.5 kW.
  • Controlling resistive loads.
  • Integration into motor starter combinations (reversing starters, wye-delta starters) using compatible SIRIUS accessories.
  • Machine and plant construction requiring a dependable and fast-wired control component.
