The ABB SPAJ140C-AA is a combined overcurrent and earth-fault relay that is used to protect electrical circuits from damage caused by overcurrent and earth faults. It is a compact and versatile relay that can be used in a variety of applications, including power distribution systems, industrial automation systems, and building automation systems.

The relay has three main functions:

• Overcurrent protection: The relay trips when the current in the protected circuit exceeds a preset threshold. This helps to prevent damage to the circuit and its components.
• Earth fault protection: The relay trips when an earth fault occurs in the protected circuit. This helps to prevent electric shock and fire.
• Signaling: The relay has a number of LEDs and contacts that can be used to signal the status of the protected circuit. This can be used to help troubleshoot problems and to provide information to other equipment in the system.

The ABB SPAJ140C-AA is a reliable and easy-to-use relay that is well-suited for a wide variety of applications. It is a popular choice for protecting electrical circuits in power distribution systems, industrial automation systems, and building automation systems.
