Abstract

The Automated High-Current Short-Circuit Test System for Miniature Circuit Breakers (MCBs) is designed to improve the safety, accuracy, and efficiency of circuit breaker testing. MCBs are important devices used to protect electrical systems from overload and short-circuit faults. The proposed system uses automation, IoT, and intelligent monitoring to test the performance of MCBs under high-current fault conditions. The system monitors voltage and current, automatically operates the MCB during testing, and records data for analysis. It also provides real-time monitoring and smart notifications to help detect possible faults and prevent equipment damage. This reduces manual effort and improves testing reliability.The system can be used in industries, testing laboratories, hospitals, data centers, and utility companies where reliable power protection is required. Overall, this solution improves testing efficiency, ensures safety, and supports the development of reliable electrical protection systems.
