Product information

Description

The Siemens SIRIUS 3RT2027-1BB40 is a high-performance 3-pole power contactor engineered for the reliable switching of electrical loads in demanding industrial environments. This S0 size contactor is designed to handle a rated operational current of 32A and operates with a 24V DC control supply voltage. Equipped with integrated 1NO and 1NC auxiliary contacts, it provides essential feedback and control capabilities for complex electrical circuits, ensuring seamless integration into modern automation systems.

Advantages

This power contactor stands out due to its robust construction and high operational reliability, which are hallmarks of the Siemens SIRIUS series. Its compact S0 design allows for efficient use of space within control cabinets without compromising on performance. The device is built to withstand frequent switching cycles, offering long-term stability and reduced maintenance requirements in industrial applications. Furthermore, the inclusion of auxiliary contacts simplifies circuit design by providing necessary status monitoring signals directly from the contactor.

Suitable for

  • Industrial motor control systems
  • Power distribution and switching applications
  • Automation and control panels
  • Heating and lighting circuit management

This contactor may not be suitable for applications requiring AC control voltages, as this specific model is designed exclusively for 24V DC operation. Additionally, it is not intended for use in environments exceeding its specified current rating of 32A or in conditions that fall outside the standard industrial temperature and humidity ranges defined for this series.

Key specifications

  • Number of poles: 3
  • Rated operational current: 32A
  • Control supply voltage: 24V DC
  • Auxiliary contacts: 1NO + 1NC
  • Size: S0

Installation should be performed by qualified personnel in accordance with local electrical regulations. The contactor is typically mounted on a standard DIN rail or via screw mounting within an enclosure. Ensure that the control circuit is correctly wired to the A1 and A2 terminals and that the main power lines are securely connected to the power terminals, observing the correct torque settings to prevent loose connections.

What to consider before purchase

  • Verify that the 24V DC control voltage matches your existing control system requirements.
  • Ensure the 32A current rating is sufficient for the intended load.
  • Check available space in your control cabinet for the S0 frame size.
  • Confirm that the 1NO and 1NC auxiliary contact configuration meets your feedback signal needs.
For optimal performance and longevity, ensure the contactor is installed in a clean, dry environment and periodically inspect the terminal connections for tightness during routine maintenance cycles.
