Product information

Description

The Siemens 3RH2140-2AP00 is a professional-grade auxiliary contactor engineered for demanding industrial control and automation environments. Built in the compact S00 size, this device provides reliable switching performance for control circuits. It features four normally open (NO) contacts and is designed to operate with a 230V AC control voltage, ensuring seamless integration into standard electrical control panels.

Advantages

This auxiliary contactor stands out due to its robust construction and the inclusion of spring-loaded terminals. These terminals facilitate rapid installation and provide a high level of vibration resistance, which is essential for maintaining consistent electrical contact in industrial settings. The compact S00 design allows for efficient use of space within control cabinets, while the high-quality materials ensure long-term operational reliability and durability under frequent switching cycles.

Suitable for

  • Industrial automation systems
  • Control circuit switching
  • Signal processing in electrical panels
  • Integration with motor starters and contactor relays

This device may not be suitable for applications requiring high-power load switching, as it is specifically designed for auxiliary control signals. It is also not intended for use in environments where the control voltage deviates from the specified 230V AC rating or where extreme environmental conditions exceed the manufacturer's specified protection class.

Key specifications

  • Size: S00
  • Contacts: 4 normally open (NO)
  • Control voltage: 230V AC
  • Connection type: Spring-loaded terminals
  • Frequency: 50/60 Hz

To use the Siemens auxiliary contactor, mount the device onto a standard 35mm DIN rail within your control cabinet. Connect the control voltage supply to the coil terminals and wire your control circuits to the four normally open contacts. Ensure that all connections are fully seated within the spring-loaded terminals to maintain a secure electrical path. Always verify that the control voltage matches the 230V AC specification before energizing the system.

What to consider before purchase

  • Verify that your control system requires a 230V AC coil voltage.
  • Ensure the S00 size fits your existing DIN rail layout.
  • Confirm that four normally open contacts are sufficient for your specific control logic.
  • Check that your wiring is compatible with spring-loaded terminal technology.

Usage recommendations

Always perform a functional test of the control circuit after installation to ensure all contacts operate correctly. Ensure that the device is installed in a clean, dry environment to prevent dust or moisture accumulation on the terminals.
