VS1i-12 intelligent medium-voltage vacuum circuit breaker is a new type of vacuum circuit breaker developed by combining traditional vacuum circuit breaker and ‘intelligent switch equipment comprehensive monitoring device’. It adopts a new modular mechanism, ensuring stable operation and simple maintenance.

The smart circuit breaker collects data from various sensors to the intelligent processor,which integrates switch mechanical characteristics, temperature data collection, and analysis functions. The display terminal performs on-site analysis of mechanical faults, temperature rise prediction alarms, and edge computing for on-site diagnostics. It supports human-machine interaction, providing strong safeguards for safe equipment operation.
