Model: TMAX | Brand: ABB
The ABB Tmax RC222/2 Differential Relay is a crucial component designed to enhance the safety and functionality of Tmax T2 circuit breakers. This residual current release module detects earth fault currents, providing protection against electrical shock and fire hazards by automatically tripping the associated circuit breaker when a fault is detected.

Figure 1: The ABB Tmax RC222/2 Differential Relay. This image displays the compact design of the residual current release, highlighting its integration with the Tmax circuit breaker series. It features clear labeling and robust construction, typical of industrial electrical components.
It is engineered for reliability and precision, ensuring compliance with international safety standards for electrical installations.
WARNING: Electrical installation and maintenance should only be performed by qualified and authorized personnel. Failure to follow these instructions can result in serious injury or death, and damage to equipment.
The RC222/2 Differential Relay is designed for seamless integration with ABB Tmax T2 circuit breakers. Proper installation is critical for its effective operation and safety.
For detailed wiring diagrams and specific installation procedures, consult the comprehensive technical documentation provided by ABB for the Tmax T2 series and the RC222/2 module.
Once correctly installed and integrated with a Tmax T2 circuit breaker, the RC222/2 Differential Relay operates automatically to monitor for earth fault currents. It continuously compares the current flowing through the live and neutral conductors. In a healthy circuit, these currents should be equal.
The device is designed for reliable, maintenance-free operation under normal conditions, acting as a critical safety component in your electrical system.
The ABB Tmax RC222/2 Differential Relay is designed for minimal maintenance. However, periodic checks are recommended to ensure continued optimal performance and safety.
If the ABB Tmax RC222/2 Differential Relay or the associated circuit breaker is not functioning as expected, consider the following troubleshooting steps:
If you are unable to resolve an issue, or if you suspect a fault with the device, do not attempt repairs. Contact a qualified electrician or ABB technical support.
