2CSR253001R1105 is an RCBO (Residual Current Circuit Breaker with Overload) manufactured by ABB. This device is designed to protect electrical circuits against short-circuits, overloads, and ground fault currents. It has a DIN Rail mount, meaning it can be mounted onto EU-standard DIN rails. It is also rated IP20, meaning it is protected from objects greater than 12.5mm in diameter. This device has 3 poles, a rated voltage of 400VAC, and current ratings of 10A Inom and 30mA Ires. In the event of a current overload or ground fault, this device will disconnect the current flow with minimal arcing, providing both personnel and equipment protection.
