Product information

Description

The Siemens SIRIUS 3RT2026-1BB40 is a high-performance 3-pole power contactor engineered for reliable industrial switching and motor control. Designed for demanding electrical environments, this size S0 device offers a rated operational current of 25A and operates with a 24V DC control supply voltage. It is built to provide consistent performance, ensuring the longevity and safety of your electrical circuits in various industrial applications.

Advantages

This power contactor stands out due to its robust construction and high operational reliability. The integration of 1NO and 1NC auxiliary contacts provides enhanced flexibility for control and monitoring circuits. Its compact size S0 design allows for efficient space utilization within control cabinets, while the standardized interface ensures seamless integration into existing automation systems. The device is optimized for high switching frequency and long mechanical service life, reducing maintenance requirements in heavy-duty environments.

Suitable for

  • Industrial motor control systems
  • Switching resistive and inductive loads
  • Automation and control panels
  • Heating and lighting control circuits

When it may not be suitable

This contactor is not intended for applications requiring AC control voltages, as it is specifically designed for 24V DC operation. It may also be unsuitable for environments exceeding the specified thermal or electrical ratings, or in hazardous areas where specialized explosion-proof equipment is mandatory.

Key specifications

  • Number of poles: 3
  • Rated operational current: 25A
  • Control supply voltage: 24V DC
  • Auxiliary contacts: 1 Normally Open (NO) and 1 Normally Closed (NC)
  • Size: S0

How to use

Installation should be performed by qualified personnel in accordance with local electrical regulations. The contactor is designed for mounting on standard DIN rails or via screw mounting within an enclosure. Ensure that the control circuit is connected to the A1 and A2 terminals with the correct 24V DC polarity. Power cables should be securely fastened to the main terminals, ensuring proper torque settings to prevent overheating. Always verify that the load current does not exceed the rated 25A capacity before energizing the system.

What to consider before purchase

  • Verify that your control system provides a stable 24V DC supply.
  • Ensure the 25A current rating matches your motor or load requirements.
  • Check available space in your control cabinet for size S0 components.
  • Confirm the auxiliary contact configuration meets your feedback or interlocking needs.

Usage recommendations

Regularly inspect terminal connections for tightness and check for signs of wear or overheating during scheduled maintenance intervals to ensure optimal performance and safety.
