Suitable for

Industrial automation and control systems

This contactor may not be suitable for applications requiring high-power load switching, as it is specifically designed for auxiliary control circuits rather than main power distribution. It is also not intended for use in environments exceeding its specified temperature or voltage ratings.

Key specifications

Contact configuration: 4 normally open (NO) and 4 normally closed (NC)
Control voltage: 24V DC
Size: S00
Application: Auxiliary control circuits

To use the Siemens auxiliary contactor, mount the device onto a standard DIN rail or a flat surface within your control cabinet. Connect the 24V DC control supply to the designated coil terminals and wire your control signals to the appropriate NO and NC contact terminals. Ensure all connections are tightened according to the manufacturer's torque specifications to prevent loose contacts and potential overheating.

What to consider before purchase

Verify that the 24V DC control voltage matches your system requirements
Ensure the S00 size fits within your existing control panel layout
Confirm that the 4NO+4NC contact configuration meets your specific logic needs

For optimal performance and safety, always ensure that the device is installed by qualified personnel and that the electrical circuit is de-energized before performing any wiring or maintenance tasks.
