[0002] Smart circuit breakers combine traditional circuit breakers with the Internet of Things to achieve intelligent management of daily electrical equipment, real-time monitoring of electrical faults and alarm or tripping, avoiding the occurrence of daily electrical fires and electric shocks, and reducing safety hazards. Smart circuit breakers use trippers for automatic tripping and communication modules for wireless communication with the outside world. The trippers and communication modules of existing smart circuit breakers are generally integrated inside the circuit breaker.
