Smart Residual Current Circuit Breaker with Overcurrent protection

Leakage current, overload and short-circuit cause harmful effects on the human body as well as electrical appliances. They may cause an electrical shock and can be sources of fire. We present in this paper a smart Residual Current Circuit Breaker with Overcurrent protection (a smart RCBO) that protects users and electrical devices against the risks of leakage current and overcurrent. The purpose of this paper is to computerize a traditional RCBO as an innovative protection device. The smart RCBO is a programmable device that works based on microcontroller technology. This device is fully automated and has adjustable settings to ensure safety while allowing increased flexibility to better match users' needs.
